It's the coolest social networking tool in the world. But is the geo-location app Foursquare a stalker's dream? Just how easy it is to uncover the intimate details of a complete stranger's life?

Louise has straight, auburn hair and, judging by the only photograph I have of her, she's in her 30s. She works in recruitment. I also know which train station she uses regularly, what supermarket she shopped at last night and where she met her friends for a meal in her home town last week. At this moment, she is somewhere inside the pub in front of me meeting with colleagues after work.

Louise is a complete stranger. Until 10 minutes ago when I discovered she was located within a mile of me, I didn't even know of her existence. But equipped only with a smartphone and an increasingly popular social networking application called Foursquare, I have located her to within just a few square metres, accessed her Twitter account and conducted multiple cross-referenced Google searches using the personal details I have already managed to accrue about her from her online presence. In the short time it has taken me to walk to this pub in central London, I probably know more about her than if I'd spent an hour talking to her face-to-face. She doesn't know it yet, but Louise is about to meet her new digital stalker.

Foursquare is the latest social networking tool to generate online buzz. The story has become very familiar in recent years: a bright young thing develops an internet app that connects people and allows them instantly to communicate with each other; within months, a million or more people around the planet are using it; investors queue up expressing an interest and speculation begins about how much Google, Yahoo!, Apple or Microsoft is willing to throw down to snap it up. (To date, the speculative figure in the media has reached $100m.)

Twitter, Facebook, MySpace and Bebo have all come before it, but Foursquare promises something new. After a decade of false dawns for the industry, it leads the way in a wave of new "geolocative" social networking tools. Unofficially, at least, 2010 has been labelled by many within the technology world as the "year of location". In addition to offering the communal connectivity of Twitter and Facebook, Foursquare also uses your smartphone's global positioning system (GPS) to broadcast your precise location to your "friends" and, should you so wish, to the wider world. Users are encouraged to "check in" on their phone whenever they arrive at a point of interest a shop, a cafe, a museum, a nightclub, an office so that fellow users know where they are. A great way supposedly to see if any of your friends are around and about. Glance down at your phone and as I did with Louise see the names of all the other users around you within a mile or so and, crucially, exactly where they are and which fellow users they are with. (I was drawn to Louise because she was in a cluster of Foursquare users albeit still rare, even somewhere such as London and she was the user allowing a stranger such as myself access to the most personal information photograph, full name, Twitter feed etc.) Visit somewhere a lot and you can even vie with other users to become its virtual "mayor". If you feel so inclined, you can also leave a tip or review in the digital ether "hey, order the bacon burger, it's great!" so others following can benefit from your experience.

Foursquare is now being widely touted as the app which will, after years of anticipation and prediction, mark the beginning of "life as a game" computing. Whatever you do, wherever you go, you will be scoring points, earning "medals", and be in, at the very least, social competition with other users around you. What the ultimate prize is, no one is yet quite sure, but some companies have been quick to realise the potential of this technology with Starbucks, Debenhams and others offering loyal customers who frequently check in to their stores rewards such as a free cup of coffee. Imagine a supermarket loyalty reward card synced with Twitter, Amazon reviews and GPS technology and you have some idea of Foursquare's potency.

But with such power comes responsibility and there are growing concerns that Foursquare is proving to be a "stalker's dream". Sure, you might earn yourself a "free" decaf latte when you check in five times at a coffee shop, but at what price to your privacy? Last month, a coding expert called Jesper Andersen managed to capture the details of 875,000 check-ins in San Francisco currently, the global hotspot of Foursquare use over a three-week period after noticing a privacy glitch in the "who was here" function which allowed him to monitor who had been checking-in to any location, regardless of the users' privacy settings.

"I'm trying to be white-hat [computing slang for a 'good guy']," Andersen told Wired.com. "It definitely felt icky at times." He had asked users he knew to confirm his findings. "Some were grossed out by it, and a couple of people stopped using Foursquare. One had a stalker and got creeped out by it."

Privacy advocates fear that Foursquare, along with other geolocation apps such as Gowalla and Google Latitude, are vulnerable to "data scraping", namely, the sophisticated trawling and monitoring of user activity in an effort to build a rich database of personal information. The big worry, say critics, is who might get to make use of this information. Pick your paranoia. Someone with criminal intent, such as a burglar, identity thief or stalker? Governments, the security services or police? Terrorists? Or a corporation looking to target its products at you with incredible precision? Compounding the threat is that "friends" are much more readily accumulated in the online world of social networking compared to who we might choose to accept as friends in our "real life". Accept a friend request in Foursquare without due care and you are potentially opening up your personal diary to a complete stranger.

Jason Stamper, editor of Computer Business Review, has criticised Foursquare for what he says is its lax attitude to privacy protection, describing the potential risks as "terrifying". Stamper's principal criticism is that Foursquare's default position on privacy is that users must "opt-out" if they don't want any of their location-based details broadcast to friends and the wider world. Of course, Foursquare would be rendered virtually useless as a tool if a user did this so there is typically always some form of data exposure occurring when someone uses Foursquare. As has been repeatedly shown before with Facebook, the risks will often boil down to whether you really know who your "friends" are.

"Many of these companies, such as Foursquare, are only paying lip service to privacy concerns," says Stamper. "Their motivation is growth. They need a critical mass of users to make their service more useful so they have to leave their doors open as much as possible.

"Privacy seems to be very low down their priorities. In theory, if every user knows the risks, this is fine. But they just don't. It's being targeted at 18 to 25-year-olds. Facebook was forced in the end to change its default privacy settings due to public concerns. Foursquare should do the same. Some people are even checking in when they're at home. Think of the implications. It's crazy."

The potential for someone to "layer" data about you is also a key concern, says Stamper. "Someone using Foursquare can accumulate a very detailed map of your habits when added to what they already know about you via Facebook, Twitter etc.

Simon Davies, the director of Privacy International, a London-based "watchdog on surveillance and privacy invasions by governments and corporations", shares similar fears about the direction this technology is taking society. "It's very difficult to extract yourself from it all once you're in. And crossing the line into live feeds of locative information is a deeply worrying step forward. Technologically, it's not a huge step, but, socially, it is huge. The big moral questions are being left to the app developers to answer at the moment. This is irresponsible. Users are being socially engineered into allowing this level of privacy invasion through the over-hyping of the benefits."

Holding the smartphone in my palm with a full-screen picture of Louise on display, I enter. Inside, a football match is showing on various screens, pints of ale and chilled lager are being pulled, and huddles of friends are bent over tables laughing and in conversation. But after several sweeps of the pub I can see no sign of Louise, or anyone even vaguely matching her picture. So I check her Twitter feed again and see she's just tweeted that she's at a recruitment networking event. I ask at the bar if there's a function room.

"Yes, downstairs."

Besides the gents, a glass-panelled door reveals a private room heaving with people in tight groups clutching glasses of wine. On a wall behind them, a large projector screen is displaying a "Twitterwall", a way of showing to an audience a feed of any particular Twitter hashtag, in this case, the name of the networking event. So I go back up to the bar, set up a Twitter account under a pseudonym on my phone, and not wishing to freak Louise out send a public message using the event's hashtag to the Twitterwall that I wish to talk to any of the Foursquare users I can see on my phone who are currently in the pub. A five-minute wait and a further tweet later, Louise sensibly accompanied by a male colleague walks up to the bar area where I'm waiting and asks if I'm the person trying to make contact. It's probably with a sense of relief that she discovers that I'm "only" a journalist investigating Foursquare.

So why does she use it? "My job in recruitment means that I try to stay at the forefront of technologies such as Twitter and Facebook," she says. "I'm just messing about with it really. To be honest, I couldn't see at first the obvious uses of Foursquare."

I then tell her the sort of information I have already managed to deduce about her life simply by using my phone. I show her that I have her own photo on my phone. She admits it's a "little unnerving, to say the least".

"I thought I was being very careful with what I was posting," she says. "I never thought I was revealing personal information. I only use my maiden name when using social networking apps. And I never check in when at my kids' school or at home. But, as you've shown, I can't see who's following me on Twitter. If I was going out for an evening with my girlfriends again, I don't think I would now share it with the world via Foursquare." (Louise's setting on Foursquare automatically tweets her location whenever she checks into a location, which was how I could tell via her Twitter feed, without being her Foursquare "friend", where she had been in recent days in such detail.)

Will she continue to use Foursquare, or at least tighten up her privacy settings? "It's just early adopters at the moment, but I can see it having excellent uses for business, particularly in my line of work. Recruitment is a form of stalking, I suppose. But I can now see the negative implications of Foursquare in the real world.

"Checking in at home is really stupid. But people can still give away clues via Twitter, as I've obviously been doing. I suppose the benefit of checking in is to create a relationship, or say to people that you've gone somewhere interesting. It's all part of social competitiveness, I suppose. It has become a habit for so many of us."

Since Andersen exposed Foursquare's privacy lapses so effectively last month, the company has made some minor alterations to how user check-in information is revealed to the public. (In March, Foursquare set up its "celebrity mode" with MTV and VH1 so that users could follow celebrity users, albeit with limited, controlled information about their location.) But a user's location can still be automatically broadcast via their Twitter feed. Critics point out that a warning of the risks should be prominently displayed to users when they set up their accounts, and they are asked if they wish to link with their Twitter and Facebook accounts.

"We're continually looking for ways to improve the sharing options that we provide," responds a Foursquare spokeswoman. "For example, we recently updated our user-settings page to create more opt-out options related to sharing user data. We are working on a number of additional changes to give users more sharing options and further clarify the implications of sharing information via Foursquare. We encourage all of our users to check their privacy settings regularly to ensure that they're comfortable with the amount of information that they're sharing."

The spokeswoman adds: "The majority of our sharing settings are opt-in users need to actively accept friend requests to be directly connected with others, and users also need to opt into broadcasting their check-ins to their Facebook and Twitter accounts at each check-in, assuming they've decided to link their Facebook and Twitter accounts to their Foursquare account."

Ten days ago Foursquare reached the two-million-users landmark, just three months after it had reached the one-million mark. A week earlier, the company received $20m in venture capital from a who's who of Silicon Valley luminaries. It appears the trajectory for Foursquare is only upwards. But as the critical mass of Foursquare users swells and intensifies over the coming months and years, the concerns over privacy are likely to magnify. In June, Webroot, a Denver-based internet security firm, surveyed 1,645 users of "geo-location-ready mobile devices", including 624 in the UK: 29% said they shared their location with people other than their friends; 31% said they accepted a friend request from a stranger; and, yet, 55% still said they were worried about their loss of privacy.

"The issue with location-based information is that it exposes another layer of personal information that, frankly, we haven't had to think much about: our exact physical location at anytime, anywhere," explained the creators of PleaseRobMe.com, a website set up to expose how vulnerable Twitter users can be when displaying location-based messages, earlier this year. "If you're comfortable being a human homing beacon, that's fine, we just want you to be fully aware of what that means and the potential risks it might involve."

Recreating existing Flash ads with HTML5/CSS3 might seem pointless, but for designers and sites looking to beat ad-blocking it might be the future. See how well you can spot the differences...

Make the HTML5 ads go away! Photo by Seeds_of_Peace on Flickr. Some rights reserved

Cover your eyes, AdBlock users: the future of the web is here, and it includes adverts.

Unless of course you reckon that Adobe's Flash is always going to reign supreme when it comes to creating animated content online, so that the combination of HTML5 and CSS3 will just never become important, or that browsers capable of displaying HTML5/CSS3 content won't become pervasive enough for it to matter.

But if you don't... over at sencha.com, you can now - assuming you're using a sufficiently modern browser - take a quiz: see if you can spot which one of the pairs of ads is done in Flash, and which is done in HTML5/CSS3. (We're not hosting them here because (a) that would be rude (b) it would be a huge hassle getting the path to the CSS files right. Off you go and take the quiz.)

Obviously, this is quite easy to figure out if you have a Flash blocker installed (or are on a platform that doesn't provide Flash - hello pretty much everyone on mobile), or if you have a browser that's not capable of displaying HTML5. But if you view it on Firefox, Chrome, Safari or Opera, you may find it tough to call.

This is encouraging, or scary, depending on your viewpoint: if designers can do things with HTML5/CSS3 that they used to need Flash for, then blocking out the messages (which has been a topic of heated debate from time to time) that help to pay for some ads become much more difficult - because it's all just HTML. (Though perhaps you then start to have "CSS-blocking" parsers which will watch for things such as ":hover" and "-animation-duration" in the CSS file - see for example the content of http://www.sencha.com/deploy/css3-ads/hertz/style.css, used for the Hertz ad recreation.

The details, if you're interested, of how to do the recreations are on another Sencha blogpost. Would-be HTML5 designers, take note.

A detailed email from the company which owns supportonclick.com and onlinepccare.com says its staff don't tell people their PCs have viruses - or they get fired. Could ex-staff be behind the scam?

Following our stories earlier this week about phone calls in which people are cold-called with claims that their PC "has a virus", we've been in touch with Pecon Software, the company behind supportonclick.com (presently shut down) and onlinepccare.com, which offer "remote PC" support. Pecon Software is based in Kolkata, an Indian city that has a lot of call centres. Quite separately, a lot of the scam sites that I've been trying to investigate seem to be linked to addresses in Kolkata, though none matching Pecon Software's address or other details.

On Monday I spoke at length to Vikas Gupta, who describes himself as the customer relationship manager for Pecon Software. Now he has sent a followup email which I'm reprinting (with the approval of himself and the company's managing director, Mahesh Kumar Shah).

On Monday I asked him about Pecon's connection with Supportonclick, which has been mentioned in a number of online forums as part of complaints about cold calls, which is registered to Pecon Software, and which was one of 19 shut down by the Metropolitan Police e-Crime Unit in April. Here's his response (I've tidied the grammar and spelling very slightly). His response is in blockquotes, my explanation/expansion in standard quote.:

"I would like to clarify a few points to you which may help you in your future articles on the same topic."

"When you called us, I did not have much information on SupportOnClick. But you took me wrong by mentioning that I denied knowing SupportOnClick. I did mention that I know Support on Click but did not know much of the history behind it."

(For clarification, Gupta told me he joined Pecon Software in November 2009. Supportonclick.com was registered in February 2006,)

"Today I had a discussion with the senior management where I requested them to tell me something about SupportOnClick. What I came to know was that SupportOnClick was our URL which we used to register customers from the UK & USA."

(Gupta's assertion is that Pecon Software would call people and offer them a remote support service, explaining what was involved, but without scare tactics.)

"You were correct that SupportOnClick's URL was suspended and the reason was that there were some complains that were reported to the UK-Police against this website."

"This was a shocking news for the management as well and we have contested this with the Registrar of the website & UK Police as well. After communicating to the UK Police for some time, they suddenly stopped answering our mails. We are still in the process of appealing to get the url unblocked. But as we already had a URL named www.onlinepccare.com which was then being used to register Australian Customers only, we started using OnlinePcCare as a single url for registering all new customers. As we had the registered customer database, we had then sent a mail to each and every customer and at the same time tried calling each and every customer to inform that they can still avail [themselves of] the service and are still giving a monthly checkup call to each and every customer that we have registered."

"We have plenty of evidence where we can prove that our services have been Helpful and Cost Effective for majority of our customers. But like any other business house, we may have not lived up to the expectations of some customers. As it was a new domain of business for us as well so with every mistake we have learnt and improved our services."

Now we come to the question of whether any of the 200-strong team (Gupta's figure, provided on Monday) of telemarketers who were cold-calling people in the UK, US and Australia offering Pecon's services ever introduced themselves as being "from Microsoft" or "Windows support services" or similarly misrepresented their reason for calling, and whether they would ever tell people from the outset that there were problems with their PC, rather than ascertaining if there were.

That's the continual complaint on multiple blogs and forums against the galaxy of sites (and, it seems, companies) that are calling people in this way. So, I asked Gupta on Monday, had Pecon Software ever found any of its staff doing this, and if it had, did it take any action? Or was the "something wrong with your machine" line part of the script for every person?

"Following the customer concerns, we took the strictest of actions against any tele-marketer who tried to mislead any customer. In many instances we have terminated such employees as well."

According to an email seen by the Guardian to Gupta from Mahesh Shah, head of Pecon Software, the company has terminated its contract with "around 30 employees in last two years."

"Some of the terminated employees did start a process of their own and we are in no position to check their operation's quality of marketing or services. But this does not mean that we are running a "Scam" or this "Business Model" is all about scamming."

It's worth noting that it would be entirely possible for someone to claim to be from any website (or company) and then direct you to a generic login site for the remote support software, notably LogMeIn, which is a legitimate product with legitimate uses, but which is used by scammers in this case to get access to your machine.

"We noticed that some of the customers went on to Blog against us. If you notice, you will seldom find any existing customer of Support on Click on these Blogs. The Blogging Community is generally Tech-Savvy and our services does not sound appealing to them. That is why they think that the cost of registration for our services are worthless. This again does not mean that we are Scamming people."

"You can also easily make out that their main concern is tele-marketing. You will find that people on blogs complain about the telephone calls that they are receiving in regards to their computer and with a preconceived notion about the subject from the various sources like print media or digital media, they suspect all tele-marketting calls to be fake or scams."

I had also pointed out that many of those blogs and forums with complaints about attempted or successful scams using this method were often then invaded by people claiming to have had marvellous experiences - but all written in similarly poor English, unlike the complainants, and with IP addresses indicating the writer was based in India.

"In reference to your question on India IP address in Blog: As I said, being a technology based Company, Pecon Software Limited would not do such a silly mistake. If you check some of the complaining Blogs are also from Indian IPs."

That's not my experience, though if anyone can find an example please put it in the comments.

"This was surely a strategic move against us from some of the "Mushroom" Companies that came into existence after being terminated from Pecon."

Gupta did suggest the names of a couple of sites that he thought were perpetrating this scam, though I can't repeat them for legal reasons just here.

I had also asked him where Pecon Software/supportonclick.com/onlinepccare.com got the names of people who were cold-called.

"In reference to List of People we call: If you remember, I did tell you that we have an SEO team which makes continuous effort to search for prospective clients and divert it to our site and apart from that we have a general tele-marketing approach to people whose names are available on Online Directories but we Remove "Do Not Call" Registered numbers from there. I have noticed that this has been the biggest concern in[comments on] your article and I can understand why."

"The wild guesses of people in blogs and the example given in your article where someone gets a call just after they have had some interaction with call centres based in India are baseless and most of the instances that I read in the blogs are mere coincidences. ISPs, Broadband services, Bigger Brands which people think are leaking data are generally associated with BPO's [Business Process Outsourcing] to international standards with all data protection security measures in place. Even a small company like ours takes data protection as a high priority issue. So there is no chance of getting any form of bulk data for tele-marketing from them."

"Tele-marketing can be annoying for many but the fact remains that it has been a successful tool of getting prospective clients. But we agree to the fact that it should not be misleading or "Earning by Deceiving" people."

"We are also equally worried if innocent people are being targeted by some group of people, and are interested to bring out the truth. This is not only the question of people in the UK or the "English-speaking world", it is also the question of the future of this industry [call centres] which millions of people are depending upon, directly or indirectly. It is also the question of reputation of call centres based in India and the BPO industry as a whole. Reputable companies such as Iyogi [remote computer support, registered in 2005, based in Delhi] and Qresolve [based in Gurgaon, registered in 2006], doing the same business, with thousands of employees may also get affected by the negativity being created by such articles or online blogs."

"We are open for any feedback which may improve operating style and suites our international audience. Your inputs will be very valuable for us."

So, what are your inputs, people?

Touchscreen computing device costing just 23 to be rolled out first to 110 million schoolchildren

India has developed the world's cheapest laptop a touchscreen device which resembles Apple's wildly popular iPad but will cost just 23.

The prototype was unveiled today by Kapil Sibal, the country's human resource development minister, who said 110 million Indian schoolchildren would be the first recipients.

Then, from next year, the device designed to bridge the digital divide and boost India's economy will become available to students in higher education.

Sibal said: "The solutions for tomorrow will emerge from India. We have reached a stage that today, the motherboard, its chip, the processing, connectivity, all of them cumulatively cost around $35 [ 23], including memory, display, everything."

Past low-cost technologies produced by the country include the 1,450 Tata Nano car and a mobile phone costing less than 11. The iPad retails at about 429 in the UK 18 times the cost of the Indian laptop.

The tablet computer, developed by researchers at the Indian Institute of Technology in Delhi and the Indian Institute of Science in Bengalooru, will eventually be made available to the public. It will run on an open source Linux operating system with Open Office software and can be powered by solar panel or batteries as well as mains electricity. It will have no hard drive but users will have access to a USB port, 2GB of memory and a video-conferencing facility, internet browsing.

Sudhir Dixit, director of Hewlett-Packard's Indian research division, welcomed the announcement. He said: "This is a very strong move with good potential. Previous initiatives with these aims have had laptops priced at around $100, so it is a development.

"The interesting thing is that slate devices are expected to come into the market and cut into sales of laptops and netbooks. The predictions are that slate devices will do to netbooks and laptops what netbooks and laptops did to desktop PCs. It gives people mobility.

"Access to IT in the education system is growing very rapidly. Because of the government's great push forward in IT, every school will have computers and, at some stage, every person will have access to IT."

More than 62m PCs are expected to be sold in India this year and the figure is predicted to top 100m in 2013. The first quarter of 2009 to the first quarter of 2010 saw a 72% growth in netbook sales.

Dixit said: "This year the IT market has begun growing very rapidly after a slump last year."

The device forms part of the Indian government's commitment to an across-the-country satisfactory standard of education by 2010. According to 2001 census figures, literacy levels in India are at 63%, lagging behind most other developing nations, including China where the figure is 93%. There are 60 million registered internet users in India, a country with a population of 1.2 billion.

Earlier this year HP Labs India announced a move to bring tens of millions of people online in the country, enabling users of low-end mobile phones to complete simple functions on websites.

The HP innovation could potentially open the customer market for small businesses from the 60 million registered internet users to the 600 million owners of mobile phones.

Microsoft announces 22% rise in three months to June
Profits near $6bn, underlining recovery in technology sector
Results beat record from rival Apple

Microsoft added to the growing sense of recovery in the technology sector last night by reporting record quarterly revenues, driven by strong sales. The software giant pipped Apple, one of its greatest rivals, with a 22% jump in revenues to $16bn ( 10.5bn) in the three months to the end of June. Operating profits jumped 49% to $5.9bn during the quarter.

The figures beat Wall Street estimates, and sent Microsoft's shares up nearly 3% in after-hours trading. But they also showed that the company is still heavily reliant on its Windows operating system and Office suite, despite years of huge investment in online services and computer gaming.

Revenues at Microsoft's Windows and Windows Live division soared by 44% to $4.5bn, with operating income up 59% to $3bn. Its business division increased revenue by 15% with operating income up 21% at $3.3bn. Analysts said the results showed that businesses have begun investing in new computers again, following the economic downturn. In contrast, losses rose at Microsoft's online services arm, which includes its MSN web portal and the Bing search engine. Revenues rose by 13% to $565m but operating losses were up 19% to $696m.

Kevin Turner, chief operating officer, acknowledged that Windows 7 and Office 10 had driven Microsoft's performance, but insisted the company was developing other strong products. Kinect is a motion-sensitive control system for the Xbox 360 that is meant to replicate the success of Nintendo's Wii system.

Microsoft reported that it has now sold 175m Windows 7 licences, while Bing has increased its share of the search market for the last 13 months.

On Tuesday, Apple cheered investors with its best-ever quarter, reporting revenues of $15.7bn. Chipmaker Intel also posted strong results on Wednesday, in a sign that PC sales were more robust than expected. Amazon, though, disappointed Wall Street after reporting a 45% rise in earnings less than analysts had expected and its shares fell 14%. Amazon also warned that its operating income would probably miss expectations this quarter.

Data summary

The first Mafia game showed promise but ultimately failed to eclipse its crime-sim rivals. Will the sequel fare any better?

For the franchise's devoted followers, it's been a long two years since Grand Theft Auto 4 came out. DLC add-ons aside, Rockstar focusing attentions on Red Dead has meant it's been quite a while since gamers have had any high-end urban sandbox fun to sink their teeth into. Crackdown and Saints Row, for all their good qualities, just weren't in the same league.

This, publisher Take 2 will hope, is where Mafia 2 steps in. Take GTA's polished gameplay, weave in classic American gangster-movie mythos, and add-in state-of-the-art graphics and meticulous attention to detail, and you have a recipe for something that's worth getting pretty excited about.

Set in a fictional American city, the game's "mature, believable" story spans two decades, as twentysomething Vito Scarletta returns home from the second world war and begins his ascent within an Italian crime syndicate.

Comparisons with its illustrious rival are inevitable, with near identical controls and gameplay mechanics, but the many ways in which Mafia 2 borrows from GTA are as much of a boon as a drawback. The absence of tricky new controls to master allows you to get stuck straight in to the action.

I was shown both the 40s and 50s Empire City in my viewing of the game - the story is split into two parts - and it's easy to see how this clever dynamic will add a great deal of depth to the experience. Cosmetically, the city changes drastically in those ten years, with the familiar streetplan reinforcing the differences - and highlighting the incredible attention to detail seen in the game as it attempts to immerse you in its iconic period setting.

Cruise around in your vehicle of choice and you're struck by just how authentic and of its time everything feels. The cars, though not actual vehicles, have been carefully designed to mirror their real-life counterparts. Meanwhile, over 100 licensed classic tunes are on offer on your suitably fuzzy sounding car radio, offering everything from Bill Haley to Frank Sinatra.

Even Vito's house, which works as a save point and garage throughout the game, has been lovingly crafted with 40s and 50s interior design, kitchen appliances, clothes to choose from and so on.

The graphics are incredibly impressive at times, and although this may have been aided somewhat by the cinema screen our preview was shown on, it looks like they're going to be amongst the best ever seen on home consoles. Much like those early, awe-inspiring panoramics over Liberty City that so impressed back in 2008, the wintry cityscape on offer at the beginning of Mafia 2 just begs to be explored.

It's this beguiling mix of attention to detail, beautiful graphics and ingenious, thoughtful touches (I noted a pair of WW2 biplanes flying overhead as you're driven from the airport in the game's opening sequence) which begins to show how Mafia 2, despite the aforementioned similarities, is a game that offers far more than a mere retro-fitted "Niko in the 50s" GTA-clone.

First off, the tone is much darker and much more serious than GTA 4. The action and set-pieces offer gritty realism rather than the more cartoony aspects of Niko's adventures in Liberty City. You certainly won't be flying off motorcycles onto helicopters at any point (well, I very much doubt it).

Towards the end of the mission I played, a gun is thrust into the mouth of one character, and you can't help but grimace as you hear his whimpers and moans before the trigger is pulled.

Meanwhile, hand combat is an altogether more challenging experience - and much more sophisticated than the punch-button jabbing of your standard GTA skirmish.

The shooting mechanics too have a more realistic feel about them. Chunks of pillar fly off as you shoot at enemies in cover, and the weaponry feels weightier, more real, somehow. Mafia 2 wants, above all else, to make you feel like you're a part of its world.

To aid this, the voice acting is, in the small section I've seen, amongst the finest ever seen in a video game. Close your eyes and you could be listening to a deleted scene from Goodfellas.

There is, however, a reason I've said you'd need to close your eyes. By opting for realism in the characters facial animations, developers 2K Czech have taken an unfortunate wrong-turn into the uncanny valley.

Although this was an unfinished version of the game, I found the static, inscrutable facial expressions featured in the cutscenes very offputting. Mouths and eyes barely move when characters are talking, lending the scenes the air of a very strange ventriloquist's act. If this prevents players from getting attached to their character, the overall game experience is really going to suffer.

This one problem aside, Mafia 2 has the makings of a blockbuster release, and is a potential must-have for your late summer shopping lists. Who knows, by the time Grand Theft Auto 5 comes out, the comparisons may be the other way around.

Look out for our full review on the Games blog in a few weeks' time.

Mafia 2 will be released on August 28th for Xbox 360, PC and PS3

With the international games industry gathered on the south coast for the Develop conference, Tech Weekly cornered legendary game designer Peter Molyneux and locked the developers behind Mass Effect, Monkey Island and the Buzz quiz series Greg Zeschuk, Tim Schafer and Caspar Field into a hotel suite together to discuss the future of gaming. Plus, one UK developer reacts to Ed Vaizey's keynote speech on government support for the games business.

If you want your free 'bumper' for iPhone 4, you'll need an app - but time limits on applications have led some to ponder whether a redesign is in the works

Want a free case - aka "bumper" - for that iPhone 4? There's an app for that. No, really: Apple has launched the program via an iPhone app (iTunes Store link) about which it says "If you are experiencing reception issues with your iPhone 4, you are eligible to receive an iPhone 4 Bumper or other selected third-party case from Apple at no charge."

Download it and you can apply. Of course, though anyone can try to (and perhaps succeed) download it, "Only iPhone 4 owners are eligible for this program" because the app will check the phone's IMEI (International Mobile Equipment Identity) number and serial number. If you bought before today (23 July), your request must be in by 22 August; other requests must be in within 30 days of purchase.

And, notes Apple, "all iPhone purchases must be made by September 30, 2010, to qualify for this program".

It's that final date - plus the news announced by Apple today, at exactly the same time as the free bumper app, that the white iPhone 4 has been delayed yet again which has some people sniffing the air and calling "hardware revision".

The white iPhone 4, after all, is (to the untrained eye) no different from the black one, except that it's, er, white. Yet Apple hasn't released any yet, which is perplexing, given that it has been making white-hued products for absolutely ages (remember the iPod?).

Apple's statement in full reads: "White models of Apple's new iPhone 4 have continued to be more challenging to manufacture than we originally expected, and as a result they will not be available until later this year. The availability of the more popular iPhone 4 black models is not affected."

Which has led some people to think that this means that inside its SECRET UNDERGROUND LABORATORY, Apple is preparing a revision of the iPhone 4 with the antenna that has caused so much woe inside the case, or at least covered up.

Personally? I think that the reason why we haven't seen white iPhone 4s is because it actually is difficult to make them. Don't forget that the main casing isn't metal or plastic; it's actually ceramic (or "aluminosilicate"). Quite possibly it actually is harder to make iPhones using that material in white.

But that doesn't answer - and Apple hasn't answered - why the free cases program only goes until September (which happens to be the end of its next financial quarter).

The chances that Apple is working on a new revision to the iPhone 4 design that puts something around the antenna? Hard to evaluate. Two things to consider:

1) Apple absolutely can do this if it wants to. It's had a few months to redesign this, and perhaps even to test it.

2) Steve Jobs reportedly loved having the antenna exposed on the outside, which might mean that the best you would get would be some sort of transparent casing or layer.

So our guidance: chances of a redesign in early October are a bit less than half, because of the Steve Jobs factor. He'd hate the idea of a design which means an acknowledgement of bad design. Plus, as John Gruber pointed out, Apple probably rather likes the idea of getting a chunk of the iPhone case business - and hates giving them away. So it might just be that by the time October rolls around, Apple's response to anyone demanding a free iPhone 4 case would be "you know, if you haven't heard about all this 'antennagate' stuff, you should have."

Wylie Agency's deal to bypass conventional publishers for digital sales is sending shockwaves around the industry

Fear and loathing among the movers and shakers of America's publishing industry have reached new heights with both Random House and Macmillan denouncing the literary agent Andrew Wylie's move into digital publishing.

Home to 700 authors and estates ranging from Philip Roth to John Updike, Jorge Luis Borges and Saul Bellow, the Wylie Agency shocked the publishing world yesterday when it announced the launch of Odyssey Editions. The initiative has been set up to sell ebook editions of modern classics including Lolita, Fear and Loathing in Las Vegas and Updike's Rabbit tetralogy exclusively via Amazon's Kindle store, leaving conventional publishers out of the picture.

The move provoked an immediate reaction from Random House, which publishes in print several of the authors involved with Odyssey Editions. The publisher fired off a letter to Amazon "disputing their rights to legally sell these titles", which it said were "subject to active Random House publishing agreements".

It went further, threatening that "on a worldwide basis", it "will not be entering into any new English-language business agreements with the Wylie Agency until this situation is resolved". It said the agency's decision to sell ebooks exclusively to Amazon "for titles which are subject to active Random House agreements undermines our longstanding commitments to and investments in our authors, and it establishes this agency as our direct competitor."

A Random House spokesman, Stuart Applebaum, told the Guardian that the severing of relations with Wylie would relate only to new book deals, while titles already in the pipeline would still go ahead. He accepted there was a risk involved for Random House, but argued that the stakes were higher for Wylie and his authors who would potentially lose a lucrative outlet for their work.

"It is not a decision that Random House reached lightly, but one that is unanimously agreed by our senior publishing colleagues in the US, Canada and the UK," Applebaum said.

Wylie's impressive client roster which includes Martin Amis and Salman Rushdie as well as the estates of Hunter S Thompson, Norman Mailer and Evelyn Waugh makes this a huge step for Random House, but one the publisher clearly felt was necessary.

At issue is who holds digital rights in older titles published before the advent of ebooks. Publishers argue that the ebook rights belong to them, and authors and agents respond that, if not specifically granted, the digital rights remain with the author.

There is also a dispute over the royalty that should be paid for ebooks: authors believe they should be getting up to double the current standard rate of 25%, because ebooks are cheaper to produce than physical editions.

As yet, none of the authors involved with Odyssey Editions have commented on the move, but Susan Cheever whose father John Cheever's stories are in the initiative said he would have been "torn".

"He was a tremendously loyal man who famously stayed at the New Yorker even when they weren't doing right by him," she told the Associated Press. "He had very good feelings about Knopf and Random House, with good reason. But in principle, I'm all for writers getting the largest percentage possible for their work."

Macmillan's US chief executive, John Sargent, hit out at Wylie's move, saying he was "appalled" by the two-year deal with Amazon, which he felt "empowers the dominant player in the market to the detriment of their competitors and creates an unbalanced retail marketplace".

"It is an extraordinarily bad deal for writers, illustrators, publishers, other booksellers, and for anyone who believes that books should be as widely available as possible. This deal advantages Amazon, which already has the dominant share in this market," Sargent wrote on his blog.

"Independent booksellers across the country are making plans to launch their e-bookstores this fall. Now they will not have these books available and Amazon will."

Andrew Wylie could not be reached for comment by the Guardian today, but he told the New York Times he had been taken by surprise by Random House's statement and had not yet decided how to respond. "I'm going to think about it a little bit," he said. "We take it seriously, as do the authors we represent. This area of discussion and negotiation needs to be resolved."

BBC Trust rules that corporation's smartphone apps do not need to pass full public value test, despite rivals' concerns

The BBC Trust has given given the all-clear to the launch of the BBC's iPhone apps despite commercial rivals' concerns about their market impact.

Smartphone applications for BBC News, BBC Sport and the iPlayer did not require further scrutiny through a public value test, it said.

The trust's review included research into the apps market by a media consultancy firm, Mediatique.

BBC trustee Diane Coyle, who led the review, said: "The apps market is rapidly taking off as more people choose to get their news, sport and other online content while they're on the move.

"The trust has a duty to represent the interests of licence fee payers, who will increasingly expect to access BBC content in this way, but also to listen to concerns raised by industry.

"In this case we have concluded that while the apps market is developing quickly and we will monitor the launch of BBC apps, a PVT is not required."

The Trust said a public value test was not required because the iPhone apps did not involve the creation of new content.

But it said the impact of the BBC services on the apps market should be monitored and would be reviewed six months after launch.

"In circumstances where the BBC's apps have an unanticipated impact on the market it will remain open to the Trust to call the proposals back in for further consideration or to consider any fair trading complaints on appeal."

The apps were in line with previous BBC activity, which already offered a range of basic web apps for mobile devices, it said, adding: "The proposals are also in line with current market trends including the growing penetration of smart phones and mobile internet usage."

Mobile phone operator reports its first quarterly service revenue growth since the recession

Strong demand for mobile data has helped Vodafone increase its service revenues for the first time in 18 months, as its key markets recovered from recession.

Britain's third-largest mobile phone operator today reported a 1.1% rise in service revenues to 10.58bn in the last three months, reversing a trend that began in the final quarter of 2008. Revenue from data services such as smartphones and high-speed internet "dongles" jumped by 25%.

"These are the first quarterly results to show service revenue growth since the global recession impacted," said chief executive Vittorio Colao.

"We have achieved these results through our continuing commercial approach in key European markets, focusing especially on data, and from strong growth in emerging markets, with India now cash-positive at an operating level and our highest ever quarterly revenue in Turkey," he added.

Colao also said that Vodafone would announce a change of strategic direction in October, to "drive shareholder value". This is understood to include a new focus on data services, especially in emerging markets like India and China.

Colao declined to give further details this morning, saying it would be "disrespectful to his board", but hinted that it may be driven by the increased number of mobile operating systems on the market today.

"The world has changed," he told reporters. "Many operating systems are strong and competing this is a good opportunity to have a look at our strategy."

Vodafone saw strong growth in demand for smartphones in Europe during the quarter, particularly in the UK where the company started selling Apple's iPhone earlier this year.

Since taking over as chief executive in summer 2008, Colao has been trying to increase growth in Vodafone's existing territories rather than continuing with the acquisition drive that has given it stakes in markets around the world.

Vodafone also announced today that it has finally resolved a long-running dispute with the UK tax authorities. This row centred on Vodafone's decision to register Mannesman, the German mobile giant it acquired in 2000, in Luxembourg.

HM Revenues & Customs had claimed that Vodafone owed taxes in Britain under the Controlled Foreign Companies rules, which the mobile operator disputed. It has now agreed to pay 1.25bn to settle the case, having previously made a provision of 3.1bn on its books.

Shares in Vodafone rose 1.88% this morning to 151.85p.

Internet freedom organisation says Ofcom draft misses vital requirements in Digital Economy Act on standards of evidence

Ofcom's draft code to cut down on illicit filesharing is flawed and should be torn up and redrafted, according to the Open Rights Group (ORG), an advocacy organisation pushing for more freedom on the internet.

The ORG said that the draft code "misses vital requirements to outline the standards of evidence" in determining whether to take action against alleged filesharers and that this means it fails to comply with the Digital Economy Act, passed at the tail end of the Labour administration, which puts an onus on Ofcom to reduce the amount of illicit filesharing in the UK.

That would mean that people might receive court summons based on evidence subpoenaed from internet service providers in which the standards of evidence of identity and action would not meet those for other offences. A persistent criticism of plans to allow copyright holders to bring people to court over allegations of illicit filesharing is the problem of creating a "chain of evidence" linking them to the offence. In the US, the music industry has been embarrassed in a number of cases where it has sued grandmothers and children, accusing them of filesharing. In the UK, lawyers acting for the Ministry of Sound have recently been sending out letters demanding payment for alleged online piracy to the puzzlement and anger of a substantial number of recipients

Ofcom's consultation closes on Friday 30 July.

The draft "initial obligations code" governs the way that copyright owners send accusations of copyright infringement to internet users under the Digital Economy Act. In some cases, this will lead to individuals being taken to court although the act itself is hazy about the details, for which the responsibility has been pushed onto Ofcom and to some extent the secretary of state for trade and industry presently, Vince Cable.

Jim Killock, the executive director of the Open Rights Group, said: "Ofcom's proposal denies us the ability to check whether any of the evidence is trustworthy. Instead, copyright holders and internet service providers will just self-certify that everything's OK. If they get it wrong, there's no penalty."

Killock notes that the draft initial obligations code does not specify how evidence of infringement of copyright should be obtained, and does not make provisions specifying the standard of evidence that must be included.

Section 3.5 to 3.7 of the draft initial obligations code outlines, in relation to evidence gathering, what it calls a "quality assurance process", but this process does not specify the means of obtaining evidence or the standard of evidence included, only that the copyright owner will have to follow the process outline in their quality assurance report which is to be submitted to Ofcom. The DEA does not require such a quality assurance system.

"The act requires the evidential standards to be defined," Killock said. "But Ofcom has passed the buck. How is anyone meant to trust this code if we can't see how the evidence is gathered or checked? Only this week, people have been apparently wrongly sent accusations of downloading tracks by the Ministry of Sound. We know things go wrong, and that's why the act requires the evidential standards to be set out."

He concluded: "What we need now is a new consultation on a new code, that is compliant with the act."

For console owners who've suddenly run out of big retail releases to play...

In video games, as in politics, nothing much happens in the summer. The publishers have finally managed to usher out all those late releases that should have been launched last Christmas, and by July, they're already looking ahead wistfully to the autumn. So unless you've saved up a little batch of neglected RPGs and epic open-world adventures, you might be forced to go outside and lob a frisbee around for the next six weeks. Shudder.

Luckily, however, downloadable digital content has come to the rescue. This summer will see a veritable picnic of digi-gaming treats on Xbox Live Arcade (which celebrates its own annual summer festival), Wiiware and PlayStation Network. Here are five to look out for...

DeathSpank
(Hothead Games, XBLA, PSN)

From the brilliant mind of LucasArts legend Ron Gilbert and widely described as 'Monkey Island meets Diablo' this beautiful, funny, challenging hack-n-slash romp was released last week, and is an absolute bloody must especially if you love the likes of Castle Crashers and The Dishwasher: Dead Samurai. Combat, puzzles, loot and gorgeous comic book art combine as you search the land for a mythical artifact, called 'The Artifact'. Great entertainment.

Limbo
(PlayDead, XBLA)

A cult hit at this year's E3 (where it was named "Best Downloadable Game" by several news sources), Limbo is a dark monochrome adventure, combining stark expressionistic imagery with some of the most imaginative environmental puzzles you've ever experienced. The hero is just a small boy on some nameless, possibly hopeless, quest and his sanguine and genuinely scary journey (especially the malicious gang of feral children), will haunt you for weeks.

Hydro Thunder: Hurricane
(Vector Unit, XBLA)

Another title from the Xbox Live Summer of Arcade, this is a sequel to the classic Midway jet boat racing game, which made an overlooked appearance on Dreamcast. I spent many a lunch hour while working on DC-UK Magazine, turbo-boosting through the intricately designed levels, searching out shortcuts. Hurricane features loads of the original boats, but all the circuits are new and there's an eight-player online mode. Woooooosh!

TerRover
(Creat Studios, PSN)

From the creator of last year's addictive Breakout clone, Magic Orbz, this is a stylised 2D puzzler, in which you pilot a wheeled droid over a series of hostile alien landscapes, picking up items and avoiding traps and obstacles. Lots of physics challenges and a nice cartoon aesthetic.

Heavy Fire: Special Operations
(Teyon, Wiiware)

Okay, I admit it, I don't know a huge amount about this one, but it's certainly intriguing. From Polish developer Teyon, Heavy Fire is an onrails shooter set in the Middle East, with players taking down insurgents while blasting the environments for extra points. There's lots of blood and destruction and, really, who could possibly not want to witness the combination of Time Crisis and Modern Warfare on the Wii?! It's out on July 26.

Parliament not doing enough to investigate privacy invasion by internet companies, Rob Halfon tells debate

A "very dangerous shift" towards a "privatised version of Big Brother" is on the horizon if UK authorities don't wake up to the invasion of privacy by internet companies, an influential Tory MP has warned.

In a debate about Google and privacy hosted by the pressure group Big Brother Watch, Rob Halfon, who is the Conservative MP for Harlow, said he believed there are many cases of privacy invasion by internet companies yet to be uncovered, and that parliamentarians need to be much more alive to the issue.

Google is facing criminal investigations around the world including in the UK for its interception of personal data about home wireless networks, taken from the company's StreetView mapping cars. The search giant admitted to accidentally intercepting extracts of personal data in May.

"The problem with Google and other big internet companies is that, despite having produced great technological advances, they have forgotten that people are individuals too," Halfon told Tuesday's debate. "We're getting into a situation where just as we're starting to get rid of the previous government's surveillance society we're now replacing it with another one: dare I say it, a privatised kind of surveillance society."

Halfon pointed to allegations of companies "trawling Facebook looking for customers saying negative things that's something worthy of the secret police. If this happened in Soviet Russia you could quite understand it."

While pointing out that he's not against private companies, the MP said more needs to be done to protect the individual: "I suspect there's a lot of privacy encroachment going on which is yet to be uncovered and that these are just a couple of stories we've just seen in the media. The reason I believe there should be an inquiry into the role of the internet and its relationship to individual liberty is because there is so much going on under the surface, tracking what we do on the internet, tracking what we say on the internet, all for commercial purposes.

"There's danger that no one will have any privacy whatsoever. And this time the threat is not from the state, it's actually private companies who have acquired the right to photograph what goes on in people's gardens. That is a very dangerous shift because we will be living, dare I say it, in a privatised version of Big Brother. That's the scenario slowly creeping up upon us."

The Metropolitan Police launched a criminal investigation into Google last month on the request of Privacy International, which alleges that the search company carried out "criminal interception of wireless communications content," constituting an offence under the Regulation of Investigatory Powers Act and the Wireless Telegraphy Act. Last month, Halfon put forward an early day motion formally requesting a House of Commons debate on "the new threat of a surveillance society".

So far, 24 MPs have signed Halfon's Commons motion, with the most prominent of them being the former shadow home secretary David Davis.

In May this year, the UK's information commissioner said he did not want to "declare war" on Google over its breach of the Data Protection Act by collecting data about home wireless networks - despite Germany, Spain, France and Italy all launching investigations under the same European legislation.

The commissioner's reaction was criticised by both Simon Davies, director of Privacy International, and Alex Deane, director of Big Brother Watch, Deane saying: "If an investigation is warranted to the criminal standard I'm not saying anyone's guilty of anything so far how can you possibly say our information commissioner should not have been looking into what was going on in this company?

"That's why I think our information commissioner has been asleep on the job, on that point. His international fellows have really put him to shame. We've got to make sure not only the people responsible for the technology are awake but also the watchdogs are awake."

Davies went further, saying the commissioner's office is "both spineless and gutless", adding: "That, unfortunately, has been the legacy of the office for a long time."

Sarah Hunter, Google's head of UK public policy, attended the event but was restricted in what she could say by ongoing legal proceedings. Hunter did say Google had taken on board privacy concerns that have arisen in the past six months and that concerns expressed at the debate would be relayed back to colleagues, adding: "The answer to a lot of these concerns is finding ways to give people control over their own personal data that's got to be at the heart of solving this conundrum.

"I think Google, or any of the responsible internet companies, understand the concerns that are expressed - how could we not be? I don't think it's true to say Google top brass don't get this. I think the last six months have been a real I think everyone's noted it, shall we say. I think we are very mindful of the challenges that the internet poses as a whole.

"At the heart of solving those challenges, we think, is giving people control over their data - giving people the capacity to both take their information away from the services, and to give people the real sense of what their information is being used for, because I don't think the internet as a platform works on an everyone-opting-in-on-every-service basis."

No date yet, but at least we know that Microsoft is admitting there are 40m Xbox 360s out there

Microsoft has announced the pricing for the Kinect bundle - you know, the you-move-it-moves system that Peter Molyneux has brought to fruition (possibly with a little bit of help).

Sitting down? OK:

"Kinect for Xbox 360, which will include the Kinect Sensor and the video game "Kinect Adventures," will retail for US$149.99 when it launches Nov. 4 in North America, the company revealed. The Kinect Sensor will work with each of the 40 million Xbox 360s currently in households worldwide."

(Useful stat, Microsoft: we'll note that 40m figure for the future.).

Oh, the UK price? 129.99. Yes! Welcome to Treasure Island - again! At the prevailing currency exchange rate, that would be 98; add on VAT at 17.5% and you get 115.40 (though once you get 20% VAT, it would be 117.60. (We're not sure what magic has been woven on the product to make the price go up as it passes over water, but make sure not to wave it over the bath.)

OK, executive quote time: Josh Hutto, director of product marketing for Xbox, said that Kinect represents a great value for new and existing Xbox 360 customers. "Kinect truly is a revolutionary product," he said. "We're bringing controller-free entertainment into the living room. With one purchase, families get Kinect and the most complete and affordable way to have fun."

So - now you know how much it is going to cost, are you going to buy one? Or are you preferring the Sony Move?

Data from the Android developers site suggests that lots of phones are running 2.1 - but there's something missing from what we're being told which may mean it's exaggerated

How fragmented is the Android platform? Google knows. And it's quite interesting. The problem is that it's not quite ready to tell us in detail. Only with winks and nudges.

The chart above comes from data on its developer site about versions accessing the Android Market for apps. A point to note: there's only one Android device out there which is running 2.2 (aka "Froyo"), and that's the Google Nexus One. Which has been discontinued.

However, some of the other phones can be upgraded to 2.2; it will be interesting to see what sort of timescale there is on that.

But what must be encouraging for the folks at Google, and Android developers, is that 2.1 is so dominant in that pie chart. (There's a tiny fraction, 0.3%, consisting of "incompatible versions" - not sure what those would be.)

Because certainly the biggest threat - and the biggest problem - for Android developers is platform fragmentation. Old version of Android can't run apps that target more recent versions, though old apps can run on the new platform. (Think of it as being like Windows. Sort of.) But the later Android versions have all sorts of features that you don't get on the others. (You can see the version feature comparison on Wikipedia.)

The timings of the version releases:

1.5: 30 April 2009
1.6: 15 September 2009
2.1: 12 January 2010
2.2: 20 May 2010

That means that this chart covers just one year (roughly).

The notable things that 2.2 has that 2.1 hasn't? Adobe Flash 10.1 support [corrected]; "remote wipe"; Wi-Fi hotspot function; voice dialling over Bluetooth. So now the question is how soon operators (particularly UK operators) will be pushing 2.2 out to Android customers. The suspicion is that the answer is "not soon", given that 2.1 only just made its way (via an over-the-air - OTA - update).

And be wary - very wary - of trusting these graphics as really indicating the preponderance of Android versions out there. What we don't know, because these graphs don't show us, is:

- whether people with newer versions of Android are more likely to access the Android Market (that would push the share for newer versions upwards: and it seems likely, since I'd be very surprised if Nexus Ones really were 3% of all Android phones sold)

- what proportion of Android apps are written for what version of Android. Although Android apps are forwards-compatible (ie if it's written for 1.5, it will run on 1.5 and every successive release), you'd certainly be put off visiting the Market if you went there once on a 1.5 or 1.6 phone and found that pretty much everything required a later version: you wouldn't go very much more. That would also push the numbers towards the later versions, and make it look like the more recent versions are doing better. (If you know any data about what proportion of apps in the Market target which version, do tell us in the comments.)

Here's how the access has changed, according to Google. But again, the same uncertainties prevail: how many? Are people put off? What's the real growth?

True, Android sales have accelerated this year and 2.1 is getting more prevalent. But that comparatively big chunk of 2.2 accesses indicates, to me anyway, that this is a distorted picture of what handsets out there are truly running.

Of course Google could help us to dispel this all by publishing how many accesses there actually were, and how many downloads. Whereas Apple likes throwing out numbers from the App Store, which gets lots of people going "ooo!", the problem is that there's nothing much to compare it with. Come on, Google, get into the game. You said there were 160,000 activations per day. Now tell us about Android Market transactions. It's the least you could do.

Well, that, and pushing the network operators and/or handset makers to push out version 2.2.

Amazon US says it has sold 143 digital books for every 100 hardbacks in the last three months

The following correction was printed in the Guardian's Corrections and clarifications column, Thursday 22 July 2010

The author of The Girl With the Dragon Tattoo is Stieg, not Steig, Larsson.

It is an announcement that will provoke horror among those who can think of nothing better than spending an afternoon rummaging around a musty old bookshop. In what could be a watershed for the publishing industry, Amazon said sales of digital books have outstripped US sales of hardbacks on its website for the first time.

Amazon claims to have sold 143 digital books for its e-reader, the Kindle, for every 100 hardback books over the past three months. The pace of change is also accelerating. Amazon said that in the most recent four weeks, the rate reached 180 ebooks for every 100 hardbacks sold. Jeff Bezos, founder of Amazon, said sales of the Kindle and ebooks had reached a "tipping point", with five authors including Steig Larsson, the writer of Girl with a Dragon Tattoo, and Stephenie Meyer, who penned the Twilight series, each selling more than 500,000 digital books. Earlier this month, Hachette said that James Patterson had sold 1.1m ebooks to date.

Neill Denny, editor-in-chief of the Bookseller, said the figures from Amazon were "eye-catching", but added a note of scepticism. He said that while ebooks had outnumbered hardbacks in volume, they were likely to be some distance behind in value. Some of the bestsellers listed on the Kindle top 10 list today were retailing for as little as $1.16 (75p). Free downloads of books no longer in copyright were excluded from the figures.

It does not appear that the growth of ebooks is damaging sales of physical books. According to the Association of American Publishers, hardback sales are still growing in the US, up 22% this year.

The association says that ebook sales in the US account for 6% of the consumer book market. One publisher in London said the US is "two or three years ahead of us. But there is no reason to suppose we won't see the same thing happening here."

Kate Pool, deputy general secretary of the Royal Society of Authors, said most authors would be "delighted" to sell large numbers of digital books. "If you speak to most authors, they couldn't bear to get rid of their old bookshelves, but if their readers want to read on an e-reader, then great. They are in it to earn a living after all."

The market is still relatively small in Britain. Digital sales were around 150m last year, says the Publishers' Association, over 80% in the academic-professional sector, with only 5m in consumer sales.

The Kindle has been available in the UK since October, although customers still need to visit the US site and get the device delivered from America.

The books catalogue is also available only through the American site and the titles priced in dollars. A spokesman said there are 390,000 titles available for UK readers to download. The company will not release figures on the number of Kindles sold. "We are nowhere near the same level as the US," Denny added. "I have never seen anyone using a Kindle in Britain. The iPad is more interesting."

Amazon cut the price of its device in June in response to the launch of Apple's iPad, which many believe could provide a substantial threat to the Kindle's market. Waterstones has sold ebooks from its website for the Sony Reader since September 2008 and will sell its one-millionth title this year, a spokesman said.

Pool said she had yet to invest in an ebook reader. "I have played around with one, but I haven't read a full book on one. It is not that I am a Luddite, more of a scrooge, which I think is the same for many people. I am waiting for the price to come down, for the amount of content available to go up and I want to be sure I am not buying the wrong thing. I don't want to be left with a Betamax when everyone else is watching VHS."

Early experiences by various testers show growing interest in new interface experience from Microsoft - but excitement is restrained

The early previews of Windows Phone 7 - for which reference hardware has started shipping to developers - are in. What to make of them? I think the best way to describe them would be a crouching ovation: people who've tried it like the fact that Microsoft is trying something different with the mobile experience, but they really can't decide if it's going to be a success or not.

Engadget's in-depth preview (an intriguing concept) is sort of positive: "Microsoft still has a few months before it intends to get the first volley of Windows Phone 7-based products to the marketplace, but we've recently been provided with reference hardware -- a not-for-retail Samsung called "Taylor" that's closely modeled on the Symbian-based i8910HD -- to get a feel for where they're at as the clock ticks down."

Quick briefs: "We were extremely surprised and impressed by the software's touch responsiveness and speed. In fact, this is probably the most accurate and nuanced touch response this side of iOS4. It's kind of stunning how much work Microsoft has done on the user experience since we first saw this interface -- everything now comes off as a tight, cohesive whole. It really put one of our major fears about Windows Phone 7 to rest. We haven't seen any substantial lag while using the device, and the short transitions between applications or pages are well suited to the overall experience."

Although: "the controversial cut-off text is still present, and while we happen to like the way it looks, it's definitely an acquired taste, and there are times when it just doesn't work, like in the Office hub where PowerPoint looks like it reads "PowerPoir." And two other things: "There are two big omissions here, in our opinion. The device won't support copy and paste, and won't support third-party multitasking of apps. We knew this would be the case given what we heard at MIX10, but it doesn't stink any less now. The former really doesn't make any sense to us, especially since Microsoft did a good job of nailing text editing and selection (at least in Word, and really... you guys make Word), and it looks like it would only be a short walk to a contextual pop-over for copy and paste functions. The latter is practically inexcusable in this day and age -- even Apple (which has been a complete laggard in this area) now supports basic multitasking."

But they like the keyboard ("the keyboard in Windows Phone 7 is really, really good. We're talking nearly as good as the iPhone keyboard, and definitely better than the stock Android option. It's one of the best and most accurate virtual keyboards we've used on any platform -- and that's saying a lot") and screen resolution ("the Windows Phone 7 standard 480 x 800").

Then again, there are points where Engadget's not so happy, which tallies with some of the doubts I expressed earlier (though I must point out that I've not held a WP7 phone, nor seen it demoed): "Windows Phone 7 doesn't have "contacts," per se -- it has a People app, and there's quite a difference. This is a thoroughly social platform, and it doesn't really seek to make any sort of differentiation between people you talk to / text / email, those you just casually observe, and those with whom you're "friends" in name only. If that kind of philosophy reeks of Motorola Blur or Palm Synergy, you're on the right track; as soon as you add a Windows Live, Exchange, or Facebook account, it pulls in every contact associated with that account and disperses associated content throughout your entire phone -- there's nothing you can do about it. That means, for example, that your Pictures app could have a bunch of shots of your ex's aunt's new boyfriend's dog in it (more on that in a bit), and there's not a whole lot you can do to stop that behavior without completely removing your Facebook account from the phone.

"With Exchange, this strategy is probably fine in most cases -- contact sync is one of the main reasons you use Exchange ActiveSync, really -- but seriously, Facebook is another matter altogether. If you've got a lot of Facebook friends, this renders your People app all but useless as a traditional phone contact list."

Over at ZDNet UK, there's another preview which goes (like Engadget) into plenty of detail: "Microsoft has stripped away all unnecessary information (almost too much, actually the status bar displaying battery life, signal strength, and so forth goes into hiding after a couple of seconds) and soft buttons, and created a Start screen that consists of 'live tiles', which are essentially dynamic widgets to your favorite apps, contacts and hubs, and also display alerts, such as new email and missed calls. You can rearrange the order of the tiles and remove them by doing a long press on the screen. You can also 'pin' new tiles, but to do so, you must first navigate to the list of apps or the People hub, find the item that you want to add and then pin it to the Start screen."

OK, and those hubs... "The names of the hubs are pretty self-explanatory. For example, the People hub merges contact information from your various accounts and then displays them in one long list. A swipe to the right will show you Facebook status updates (unfortunately, Windows Phone 7 will not have Twitter or MySpace integration at launch) and lets you add comments, while another swipe will brings up the people you've contacted most recently."

"This type of panoramic UI runs across all the various hubs with bold, attractive text splashed across the top to identify different subsections (a.k.a. Pivots) and in some cases, a small contextual toolbar along the bottom of the screen to help you perform app-specific tasks."

"Some might complain that this type of navigation requires too much scrolling and can be overly complicated. Admittedly, this is true when compared to Apple's iOS 4 and Google's Android, and may be a turn-off for consumers. On the other hand, we appreciate the ability to do so many things from one place without having to launch several different apps, so we have to give Microsoft kudos for thinking of this kind of organisation. We also like the consistent UI, which makes it easy to work the other hubs."

Another point which has been made elsewhere: "What's interesting about Windows Phone 7, though, is that at times it feels as though you're getting two completely different experiences on one phone. The Start screen/menu list and some apps such as the phone dialer, email inbox and calendar are completely minimalistic, while other aspects of the phone, including the aforementioned hubs and multimedia features, are more sophisticated and elegant. It doesn't hurt the navigation, as such, but is doesn't make the phone feel like a cohesive unit either."

And the big question: "Will this resonate with users? Frankly, we think it'll be a hard sell initially. Despite all the improvements made to the UI, it's still more involved than other operating systems. That said, we'd also caution you not to dismiss it completely, simply because it's different. Change is scary, but it can also be a good thing."

It's a long review, which you're urged to read in detail.

Meanwhile the Wired Gadgetlab has put its sticky fingers all over the screen: here's the video. Their principal comment: "Still the lack of any kind of real app store is a major hindrance. Also, Microsoft just will not give up on the Zune marketplace. It's admirable, but maybe they should re-examine their reasoning for keeping it." But surely the Zune Marketplace is Microsoft's leg up to an App Store? Abandoning it would look weird.

Watchdog says Cardiff councillor John Dixon's Twitter message 'likely' to have breached code of conduct for local authority members

A councillor is facing a disciplinary hearing after calling the Church of Scientology "stupid" on Twitter, it emerged today.

The Welsh public standards watchdog investigated Cardiff councillor John Dixon's short message and decided it was "likely" to have breached the code of conduct for local authority members.

News of the ombudsman's decision prompted a flood of messages of support on Twitter for Dixon, the council's executive member for health, social care and wellbeing.

Tweets included an offer to find a lawyer to fight his case pro bono and many others defending his right to free speech.

The case centres on a message posted by the Liberal Democrat councillor during a visit to London.

It said: "I didn't know the Scientologists had a church on Tottenham Court Road. Just hurried past in case the stupid rubs off."

The message was posted on an account called CllrJohnDixon. He has since set up a second account, JohnLDixon, for his "more personal musings", in which he describes himself as a "microbiologist and web developer, into science, rugby and web geekery".

By 3pm today, Dixon's number of followers on Twitter had trebled.

One supporter said: "Instead of a disciplinary hearing, they should canvas all the electorate to see if they agree with you. I think they just might."

Another wrote: "We're all behind you mate, if any disciplinary action goes ahead it will be because the stupid rubbed off on someone."

Dixon later tweeted: "Just seen all the retweets about my ombudsman's judgement. Um... Wow... Thanks."

A spokeswoman for the Public Services Ombudsman for Wales confirmed there had been an investigation into Dixon.

The investigation had found there was likely to have been a breach of the code of conduct local authority members must follow.

The ombudsman has referred the case to Cardiff council's standards and ethics committee, which will consider it in the autumn. It will have to decide if there has been a breach and, if it finds there has been, consider any sanctions.

A spokesman for the Church of Scientology said: "The complaint was made by an individual Scientologist who was personally offended by the comments."

The spokesman suggested people go to their website to find out about the church and its founder, L Ron Hubbard.

Dixon argued that the remarks were made in a personal capacity rather than as a councillor, and said his Twitter name was CllrJohnDixon only because JohnDixon had been taken.

He told the Guardian he was in London in June last year to buy a wedding ring for his wife-to-be which he also tweeted about. Other postings made at the time included remarks about visiting a relative in Richmond and going to a musical.

Dixon said he thought the remark about the Church of Scientology was "whimsical" and had thought nothing more about it until he began to suspect that members of the church were following him on Twitter.

He posted another message: "Just realised the Scientologists are following me. Quick everyone, pretend you're out."

But he said that, in December, the ombudsman received a complaint about the remarks. Councillors are obliged to carry out their duties with due regard to the principle that there should be equal opportunity to all, regardless of their religion.

Dixon said that even if he had been speaking in an official capacity which he maintains he was not he was surprised at the complaint going so far.

"As a Liberal Democrat, I'm used to having things said about me. You take it on the chin," he said.

He said he did not have very strong opinions on Scientologists before the saga. "Having done some research on them, I take a harder line now," he added.

Lawyers for Ministry of Sound and other music labels are seeking compensation, threatening court action unless file sharers pay

Solicitors for dance music label Ministry of Sound have sent letters to thousands of internet users it believes have illegally downloaded music and says it is determined to take them to court and extract substantial damages unless they immediately pay compensation, typically around 350.

Ministry of Sound's move marks an intensification of the legal battle against file sharers, which is seeing more and more lawyers send out what critics call speculative invoicing of downloaders suspected of pirating anything from music tracks to films and games.

Soho firm Gallant Macmillan last week completed a mailout to 2,000 individuals it claims infringed Ministry of Sound's copyright after downloading and sharing music. It follows in the steps of ACS:Law, which has sent many thousands of letters demanding compensation from alleged file sharers, sometimes billing in excess of 1,000. Luke Bellamy, above, contacted Money this week after receiving a 295 demand from ACS:Law, which alleged he downloaded and shared a track from dance music group Cascada.

Some recipients of the letters, concerned about forking out huge damages, have paid up. Others have been mystified they claim never to have downloaded the tracks. Meanwhile, some legal specialists say the threats are largely unenforceable. Unless a user confesses to illegally downloading a file, or a court order is obtained to seize a computer and the file is then located on its hard drive, consumer groups say, it's hard to see how such an action will succeed.

Even the body that represents the UK recorded music industry, the BPI, which is keen to stamp out illegal filesharing, says it does not condone the mass-mailing of alleged internet pirates. "Our view is that legal action is best reserved for the most persistent or serious offenders, rather than widely used as a first response," it says.

Most recipients of the letters have binned them and, to date, avoided any further action. But Gallant Macmillan says it is taking a different approach to the other legal firms that pioneered this business, and that its sole client, Ministry of Sound, is serious when it threatens legal action. Until now, none of these cases have ended up in UK courts. A Ministry of Sound spokesman says that actions have been won in German courts, and it is confident that it can do the same in the UK.

Bellamy, 23, a lifeguard from Dudley, West Midlands, lives with his parents, but pays for the O2 broadband connection into the family home. The letter sent to him by ACS:Law claims his internet account was used to download Evacuate the Dancefloor by Cascada, from the filesharing website uTorrent.

The letter, which runs to nine pages, goes on to claim that this was in breach of ACS's clients' copyright, and offers to settle its potential claim if Bellamy pays nearly 300 in compensation.

"Getting a letter like this is extremely worrying. I have never downloaded anything from this website and yet I am being chased for this money. My parents have been worried by this, and frankly I've got better things to do with my time than deal with this."

And he is by no means alone. The internet is awash with similar complaints from anxious web users - many of whom who did download the files where they have been accused of infringing copyright, but also from plenty who insist they didn't. The letters demand anywhere between 300 and 1,200. The law firms sending the letters obtain the names and addresses of the downloaders from internet service providers (ISPs). To get access, they usually seek a high court order, and ISPs have no choice but to hand over the details.

In November 2008, Money first reported that solicitors were sending out threatening letters to net users. We featured a Hertfordshire couple sent a demand to pay 503 for "copyright infringement" or face a high court action. The 20-page "pre-settlement letter" from legal firm Davenport Lyons demanded money on behalf of German pornographers, who claimed the pair had illegally downloaded a porn film. The couple said they had no idea how to even download a film, even if they had the inclination, which they didn't.

Michael Coyle, solicitor advocate and MD of the Southampton-based law firm Lawdit, who has represented hundreds of people who have received these letters, says none of his cases have gone to court.

"A significant number of cases were connected to porn, seeking to embarrass porn users into paying up, and it developed from there. Perhaps as many as 10% of those receiving letters have paid up, but the rest have just disappeared. These firms are trying to argue that just because you pay for the internet connection you are somehow responsible for everything that is downloaded on it whether you were responsible or not. It just doesn't stand up in law," he says.

"It seems to me that the only way a claim can be upheld is if you admit it or if they inspect your hard drive."

He is so confident that a claim by the likes of ACS:Law would not succeed that he has offered to defend anyone in court for free providing they didn't download the offending file.

Following a complaint by consumer group Which? (and others) Davenport Lyons, the law firm which pioneered the approach in the UK, is facing a probe by the Solicitors Regulation Authority. Which? says it has had 200 complaints from the public on this issue, and has several pages on his website advising consumers what they should do if they receive such a letter.

"Remember that you have to be actively involved to be guilty of copyright infringement," it says.

"If you're not, explain why and ask for the proof that positively identifies you as the culprit. They may make counterclaims or raise other issues when they reply but concentrate on making them prove it was you." Which? recently warned those affected not to reply to a request by ACS:Law to fill in a questionnaire the company apparently sends to all those who deny any involvement.

Deborah Prince, head of legal affairs at Which?, says people are under no obligation to fill in these questionnaires. "Which? believes it is outrageous that ACS:Law is asking consumers to provide evidence to support the claims that it is making on their clients' behalf. It should have all the evidence it needs before making these allegations. If it doesn't, then it shouldn't be asking unrepresented consumers to provide that evidence."

Andrew Crossley, head of ACS:Law, says his letters do not accuse the recipients of "downloading".

"We have written to your reader, as with everyone else we have written to, informing them that we have evidence one of our clients' copyrighted works was made available through a filesharing network to others from the internet connection they have.

"In other words, the work was uploaded, not downloaded, and is distributed many times over and given to others who in turn make it available to many others.

"All this is done without reference to the copyright owner, who receives no payment for this often repeated transaction, denying our clients income."

He says the amount demanded in the letters is a fraction of the damages that would be awarded in a successful civil action for copyright infringement, and claims illegal filesharing has been devastating to the creative industries.

He declined to comment on how many cases had gone to court, but said: "I can confirm proceedings have been issued and that more proceedings are to be issued in increasing numbers.

"The amount we request in compromise is a token payment to reflect some small amount of the losses of our clients to illegal filesharing."

Soft-drinks giant reviews relationship with firm that created Dr Pepper campaign featuring 'offensive' Facebook status updates

Coca-Cola is considering cutting ties with the agency that created a Facebook campaign that parents accused of targeting children by using references to a notorious pornographic movie.

The soft-drinks giant, which has come in for heavy criticism after running a racy Facebook campaign for the Dr Pepper brand, has told the agency that it must stop all advertising work on Coca-Cola brands until a decision is reached on whether to terminate the relationship.

"We have stopped all our ongoing work with [digital agency] Lean Mean Fighting Machine and are currently reviewing our relationship with the agency," said a spokeswoman for Coca-Cola GB.

The company was forced to pull a Facebook campaign for its Dr Pepper brand, in which users allowed their Facebook status box to be taken over by the company. Users could choose from three levels of "embarrassingness", and the contract with Facebook stipulated that all content had to be moderated by Coke before going live.

However, the promotion backfired when a Mumsnet user saw her 14-year-old daughter's Facebook page or rather the Dr Pepper campaign she had joined had been updated with a message that made direct reference to a hardcore pornographic film.

Coca-Cola apologised and announced an investigation into its promotion procedures.

It said the offending line had been approved by them, without them realising its true meaning.

Other examples of embarrassing statuses used as part of the promotion included: "Lost my special blankie. How will I go sleepies?", "What's wrong with peeing in the shower?" and "Never heard of it described as cute before."

Coca-Cola is now reviewing its relationship with the agency behind the campaign, Lean Mean Fighting Machine. The move could result in the agency losing one of advertising's juiciest accounts a bitter blow, especially as it had just won the digital ad account for Coca-Cola's Coke Zero brand.

Dr Pepper is no stranger to flirting with social media controversy in its marketing activity, which uses the strapline "What's the worst that can happen?". For April Fool's Day the brand launched a push on Chatroulette featuring a cheerleader.

Deadline for broadband in all UK homes by 2012 put back by Tory culture secretary Jeremy Hunt, who says Labour's plan was impractical

The battle to close Britain's broadband divide suffered a blow today when the government pushed back the UK's target for universal access to high-speed networks by three years.

Jeremy Hunt, the culture secretary, said that it was not practical to meet the previous government's target of universal broadband coverage by 2012 a commitment he had previously dismissed as "paltry". Instead, Hunt said it would take until 2015 before every home in Britain had at least a 2Mbps (megabits per second) connection.

Speaking at the start of an industry day that was meant to find solutions to Britain's broadband coverage problems, Hunt claimed the previous government had not funded its 2012 commitment properly.

"I have looked at the provision the government had made to achieve this by 2012. And I'm afraid that I am not convinced that there is sufficient funding in place," Hunt told a gathering of telecoms operators. "So, while we will keep working towards that date, we have set ourselves a more realistic target of achieving universal 2Mbps access within the lifetime of this parliament."

Sebastien Lahtinen of telecoms site Thinkbroadband.com, described Hunt's move as a shock and a "significant setback for rural broadband users".

Jillian Pitt, broadband expert at Consumer Focus, said the decision was a blow. "Often people living in these remote communities are amongst the most disadvantaged in our society, so there is also a wider issue about suppliers ensuring that broadband is not only available, but also affordable," she said.

At present, 99% of homes can get some form of broadband connection but about 11% or 2 million homes cannot get speeds as high as 2Mbps. This limits their ability to use bandwidth-intensive services such as video streaming and television-on-demand. About 160,000 rural and remote households still cannot get any form of broadband, more than 10 years after the first services were launched.

Labour had assigned about 250m from the digital switchover fund to pay for its universal service obligation. It had also planned to introduce a 50p-per-line levy on all phone lines to fund the rollout of superfast networks in rural areas, but this tax was shelved before the election and then abolished by George Osborne in June's budget.

Hunt's message to the telecoms industry was that it was essential that the next generation of broadband networks, which offers speeds upwards of 40Mbps, were made available to "virtually every household". He wants Britain to have the best superfast broadband in Europe by 2015.

However, the government also expects the communications sector to take the lead, even though companies such as BT have warned that it is not economically viable to extend superfast broadband across the whole country.

BT Openreach's chief executive, Steve Robertson, has predicted that 2bn of state funding would be needed to achieve universal fibre-optic coverage in the future, and avoid a new divide in the future between those who can get the fastest services and those who cannot.

Hunt, though, said that innovative solutions were the answer. "I don't want to hear about how to roll out a fibre-optic pipe to every home in Wales," said Hunt, who suggested the water mains and sewers could be opened up if this would cut the cost of building new networks.

He also conceded that commercial operators could not solve the problem alone. "There is market failure now so I believe there will be market failure in the future, but I would be incredibly pleased to learn that this is not the case."

BT has committed to spending 2.5bn to extend its new fibre network to two-thirds of homes, but has warned that it cannot go further without government support.

Broadband is an important subject for many politicians, especially those whose constituencies are riddled with blackspots. Rory Stewart, Conservative MP for Penrith, suggested that telecoms operators should be given access to networks run by state bodies such as the Ministry of Defence, the NHS or the education sector.

Caroline Spelman, the environment secretary, said that this idea would raise security issues, but agreed that public-private partnerships could be set up to make better use of public infrastructure.

The government also said today that it would start three trials of super-fast broadband networks in rural areas this autumn. These pilots should identify ways of bringing broadband to areas where it is not economically viable through partnerships, funding support, or by relaxing legislation.

Martha Lane Fox, the UK's digital champion, also attended the industry day. She said it was essential that Britain achieved universal broadband coverage at 2Mbps as soon as possible. "I know fibre rollout is important, but I personally think we can do a lot by hitting the universal service commitment," she said.

We talk to WoW's lead designers about the history and future of the Warcraft universe

Designing an MMORPG is a unique creative challenge. The initial game universe can take up to five years to build and often requires the formation of a complex mythology to provide and maintain its narrative thrust through future add-ons and expansion packs. In this sense, it's more like working on a TV series than a game the design team just keeps writing new content, expanding the story, while hopefully attracting newcomers and it can go on for years.

So how does a development studio remain fresh, engaged and creative on such a lengthy and precarious production line? And where do they get their ideas? To find out, I spoke to three WoW veterans: lead designer Tom Chilton, lead content designer Cory Stockton and lead systems designer Greg Street. Here, they talk about the influences behind World of Warcraft, and some of the concepts they're taking onboard for the future of the game...

So what were the key influences behind World of Warcraft when Blizzard started out on the project?
Tom Chilton: It was most heavily influenced by the early MMOs. At the time, a lot of people at Blizzard were playing games like Ultima Online, Everquest and Dark Age of Camelot, and were really into that kind of game. The WoW team originally started off with a different project they were making a game called Nomad, a role-playing game, but the decision was made that it was not making the progress we wanted. So one day we announced: "You're no longer working on Nomad, now you're going to make World of Warcraft!"

And what are your key inspirations for the mythology and narrative elements on the game?
TC: It's a combination of a lot of things. We're absolutely influenced by Dungeons and Dragons, and Tolkien, we're influenced by movies and not just movies with fantasy settings, we're influenced by contemporary and sci-fi movies. All that plays a role.

Cory Stockton: We all look to film, we look at the grand sets and think, "wow, that's crazy, how could we translate that?" Seeing something like Avatar or Lord of the Rings, it's just the way they can take a space and make it feel alive. We're influenced by tons of games and not just MMOs. I've always been a console gamer, so for me, I see Metroid, which has lots of exploration and discovering new things, and I see a lot of Zelda in WoW.

Look at some of the boss fights we're doing nowadays compared to way back. One of our first raid boss fights, Ragnaros he's stuck in a room and barely moves, the room never changes. But you look at the fights we do now, we have bosses who break down walls; you can break off parts of their limbs, then that falls through the floor, and the player jumps through too. If you think of the Zelda bosses, they interact with the whole environment. When I look at WoW, that's what I think of, the action adventure genre. You've got to get the MMO part of it out of your head. For a player, when they're doing a dungeon or a quest, there's no reason that you can't do things you can do in a console game. It's the idea of erasing those barriers.

There are definitely some areas that have reminded me of Super Mario 64 and Prince of Persia the way you need to plan your way through the environment
TC: Exactly, and I think you're going to see more of that in Cataclysm, and that's because our toolsets have got so much better. We tried to do some of that stuff in the past, but it probably wasn't as polished as we would have liked; now, with our vehicle system, we can do so many more things. And they're not even just vehicles; we can use the system to have you grab a rope and swing on to a pirate ship that's done using the vehicle system, but to the player that's all invisible, it just feels like a cool mechanic.

And just like Nintendo's games, the idea of balance is vital?
Greg Street: My background prior to Blizzard was working on real-time strategy games and that was 100% about unit balance, making sure characters felt unique but not over-powered. I approach it like a maths puzzle. Things need to have a budget if a spell is too expensive no one is going to want to use it, or if a spell does the exact same thing as another one it's not going to be attractive. It's almost like bringing the economy of an RTS into an MMO.

We've talked about games and genres that you've all been inspired by, but are there any star game designers you look up to? Maybe the likes of, say, Richard Bartle or Raph Koster?
CS: I look up to Miyamoto, I look up to Sid Meier. It's not just their games, it's their philosophies on game design. With Miyamoto, it's the idea that control is king whatever crazy ideas he has for games what always matters is that the controls are unbelievable.

We have the same design philosophy at Blizzard. When we do something in WoW, it's got to feel instantly reactive, it can't feel laggy, it can't feel confusing. Something as simple as the jump you see people jumping about in WoW all the time and the reason they do that is because we tuned the living crap out of it. The animations are tuned exactly right, the way we send those commands over the server, we have prioritisation on stuff, so certain animations will play smoothly. And we have randomness built into that, in the way the night elf does an occasional front flip. A jump animation isn't just that, it has multiple alternatives. And no one would think that a jump animation matters that much, but we put in so much effort because we knew players would be doing it all the time.

With Sid Meier, you get the influence on the overall game as a whole. He's got this theory of each game taking one third prototype, one third crazy ideas, one third proven ideas, and you put those together and you see a game evolve.

How would you describe the development process on WoW these days?
GS: We tend to work from these very long task lists of ideas. When we have a new idea, we put it on the list then we spend time either bumping them up or bumping them down. In the software we use to track our tasks we're in numbers like 20-30,000 ideas. And we'll see an item at number 5,000 that's just been bumped for years and years, and maybe some day we'll do it, of if the game has gone in a different direction, we just delete it. So for every patch we'll get the list out and say, "okay, is there anything on here we want to try to get in?" Often it just takes a designer who's very passionate about something. People have a lot of power on the team to just push something they're very excited about, to get it in the game. Often all it takes is one champion to get the ball rolling.

How do new features get implemented is the process led by the programmers or the design team?
CS: Basically, we come up with a crazy idea, and then it comes down to, can [the coders] implement it?! If they can't then we ask, "what can we get?" And then it's down to time how long will it take to get this done? We come up with a bit list and just see if we can implement it. A great example would be when we added flying to Burning Crusade that was the biggest addition to WoW at that point it was a huge programming task. We knew we had to have it, it was the key back-of-the-box feature, but it was clear we'd take a super long time to get it, which meant there were a couple of other things we couldn't do. But we had to decide, what will make the biggest impact for the players?

How much of the current design work is based on watching emergent player activities in the game world and thinking, "hey we should actually support that more fully?"
CS: It totally happens, both from playing the game ourselves and watching other people play. A good example would be Wintergrasp, which was our open-world PvP zone in Northwind. It was the first time we'd ever done something like that, it was PvP but it wasn't in an instance, so any one could come. And it was really crazy, getting it into the game, and it turned out to be one of the most popular parts of the Wrath of Lich King overall.

But we made a massive number of changes to it after it went into the game because people were playing it in very different ways than we expected. We had a system where you had to get a certain amount of honourable kills to get vehicles, but the players ended up doing something completely different to get vehicles so we modified the whole system. The way that they were attacking the bases was way different to how we had planned. The problem with something like that is, with the beta it's hard to get critical mass of people to play it, but when it goes on the server and you have a thousand people going on there at one time, a group mentality works very differently to a small number of players. Definitely, with things like that, we just make updates with every patch. Now we haven't touched it for a while, because it's running exactly how we want.

TC: I'd say most of what we do now is driven by player feedback. It might be feedback we've been hearing since six years ago and we only now have an opportunity to do it, and sometimes it's things that have come up recently. And as you'd expect there are way more ideas than we ever have time to do.

Part two tomorrow

Text, text, text, that's all they think about: but are all those hours on the phone and Facebook turning teenagers into screen-enslaved social inadequates? Jon Henley finds out

"I'd rather," deadpans Philippa Grogan, 16, "give up, like, a kidney than my phone. How did you manage before? Carrier pigeons? Letters? Going round each others' houses on BIKES?" Cameron Kirk, 14, reckons he spends "an hour, hour-and-a-half on school days" hanging out with his 450-odd Facebook friends; maybe twice that at weekends. "It's actually very practical if you forget what that day's homework is. Unfortunately, one of my best friends doesn't have Facebook. But it's OK; we talk on our PlayStations."

Emily Hooley, 16, recalls a Very Dark Moment: "We went to Wales for a week at half term to revise. There was no mobile, no TV, no broadband. We had to drive into town just to get a signal. It was really hard, knowing people were texting you, writing on your Wall, and you couldn't respond. Loads of my friends said they'd just never do that."

Teens, eh? Not how they were when I was young. Nor the way they talk to each other. Let's frighten ourselves, first: for a decade, the Pew Internet & American Life Project has been the world's largest and most authoritative provider of data on the internet's impact on the lives of 21st-century citizens. Since 2007, it has been chronicling the use teenagers make of the net, in particular their mass adoption of social networking sites. It has been studying the way teens use mobile phones, including text messages, since 2006.

This is what the Project says about the way US teens (and, by extension, teenagers in much of western Europe: the exact figures may sometimes differ by a percentage point or two, but the patterns are the same) communicate in an age of Facebook Chat, instant messaging and unlimited texts. Ready?

First, 75% of all teenagers (and 58% of 12-year-olds) now have a mobile phone. Almost 90% of phone-owning teens send and receive texts, most of them daily. Half send 50 or more texts a day; one in three send 100. In fact, in barely four years, texting has established itself as comfortably "the preferred channel of basic communication between teens and their friends".

But phones do more than simply text, of course. More than 80% of phone-owning teens also use them to take pictures (and 64% to share those pictures with others). Sixty per cent listen to music on them, 46% play games, 32% swap videos and 23% access social networking sites. The mobile phone, in short, is now "the favoured communication hub for the majority of teens".

As if texting, swapping, hanging and generally spending their waking hours welded to their phones wasn't enough, 73% use social networking sites, mostly Facebook 50% more than three years ago. Digital communication is not just prevalent in teenagers' lives. It IS teenagers' lives.

There's a very straightforward reason, says Amanda Lenhart, a Pew senior research specialist. "Simply, these technologies meet teens' developmental needs," she says. "Mobile phones and social networking sites make the things teens have always done defining their own identity, establishing themselves as independent of their parents, looking cool, impressing members of the opposite sex a whole lot easier."

Flirting, boasting, gossiping, teasing, hanging out, confessing: all that classic teen stuff has always happened, Lenhart says. It's just that it used to happen behind the bike sheds, or via tightly folded notes pressed urgently into sweating hands in the corridor between lessons. Social networking sites and mobile phones have simply facilitated the whole business, a gadzillion times over.

For Professor Patti Valkenburg, of the University of Amsterdam's internationally respected Centre for Research on Children, Adolescents and the Media, "contemporary communications tools" help resolve one of the fundamental conflicts that rages within every adolescent. Adolescence, she says, is characterised by "an enhanced need for self-presentation, or communicating your identity to others, and also self-disclosure discussing intimate topics. Both are essential in developing teenagers' identities, allowing them to validate their opinions and determine the appropriateness of their attitudes and behaviours."

But, as we all recall, adolescence is also a period of excruciating shyness and aching self-consciousness which can make all that self-presentation and self-disclosure something of a perilous, not to say agonising, business. So the big plus of texting, instant messaging and social networking is that it allows the crucial identity-establishing behaviour, without the accompanying embarrassment. "These technologies give their users a sense of increased controllability," Valkenburg says. "That, in turn, allows them to feel secure about their communication, and thus freer in their interpersonal relations."

"Controllability", she explains, is about three things: being able to say what you want without fear of the message not getting through because of that humungous spot on your chin or your tendency to blush; having the power to reflect on and change what you write before you send it (in contrast to face-to-face communication); and being able to stay in touch with untold hordes of friends at times, and in places, where your predecessors were essentially incommunicado.

But what do teenagers make of this newfound freedom to communicate? Philippa reckons she sends "probably about 30" text messages every day, and receives as many. "They're about meeting up where are you, see you in 10, that kind of thing," she says. "There's an awful lot of flirting goes on, of course. Or it's, 'OMG, what's biology homework?'. And, 'I'm babysitting and I'm SOOOO bored.'" (Boredom appears to be the key factor in the initiation of many teen communications.)

Like most of her peers, Philippa wouldn't dream of using her phone to actually phone anyone, except perhaps her parents to placate them if she's not where she should be, or ask them to come and pick her up if she is. Calls are expensive, and you can't make them in class (you shouldn't text in class either, but "lots of people do").

Philippa also has 639 Facebook friends, and claims to know "the vast majority" (though some, she admits, are "quite far down the food chain"). "I don't want to be big-headed or anything, but I am quite popular," she says. "Only because I don't have a social life outside my bedroom, though." When I call her, 129 of her friends are online.

Facebook rush-hour is straight after school, and around nine or 10 in the evening. "You can have about 10 chats open at a time, then it gets a bit slow and you have to start deleting people," Philippa says. The topics? "General banter, light-hearted abuse. Lots of talk about parties and about photos of parties." Cred-wise, it's important to have a good, active Facebook profile: lots of updates, lots of photos of you tagged.

Sometimes, though, it ends in tears. Everyone has witnessed cyber-bullying, but the worst thing that happened to Philippa was when someone posted "a really dreadful picture of me, with an awful double chin", then refused to take it down. "She kept saying, 'No way, it's upped my profile views 400%,'" says Philippa. It's quite easy, she thinks, for people to feel "belittled, isolated" on Facebook.

There are other downsides. Following huge recent publicity, teens are increasingly aware of the dangers of online predators. "Privacy's a real issue," says Emily. "I get 'friend' requests from people I don't know and have never heard of; I ignore them. I have a private profile. I'm very careful about that."

A 2009 survey found up to 45% of US companies are now checking job applicants' activity on social networking sites, and 35% reported rejecting people because of what they found. Universities and colleges, similarly, are starting to look online. "You need to be careful," says Cameron Kirk, astute and aware even at 14. "Stuff can very easily get misunderstood." Emily agrees, but adds: "Personally, I love the idea that it's up there for ever. It'll be lovely to go back, later, and see all those emotions and relations."

Pew's Lenhart says research has revealed a class distinction in many teens' attitudes to online privacy. "Teens from college-focused, upper-middle-class familes tend to be much more aware of their online profiles, what they say about them, future consequences for jobs and education," she says. "With others, there's a tendency to share as much as they can, because that's their chance for fame, their possibility of a ticket out."

The question that concerns most parents, though, is whether such an unprecedented, near-immeasurable surge in non face-to-face communication is somehow changing our teenagers diminishing their ability to conduct more traditional relationships, turning them into screen-enslaved, socially challenged adults. Yet teens, on the whole, seem pretty sensible about this. Callum O'Connor, 16, says there's a big difference between chatting online and face to face. "Face to face is so much clearer," he says. "Facebook and instant messaging are such detached forms of communication. It's so easy to be misinterpreted, or to misinterpret what someone says. It's terribly easy to say really horrible things. I'm permanently worrying will this seem heartless, how many kisses should I add, can I say that?"

He's certain that what goes on online "isn't completely real. Some people clearly think it is, but I feel the difference. It's really not the same." Emily agrees: "It's weird. If I have a massive fight on Facebook, it's always, like, the next day, did it actually matter? Was it important? I always go up to the person afterwards and talk to them face to face, to see their emotions and their expressions. Otherwise you never know. It's complicated."

Emily is fairly confident that social networking and texting aren't changing who she is. "I'm the same online and in person. All this is an extension to real life, not a replacement." Olivia Stamp, 16 and equally self-aware, says she thinks social networking actually helps her to be more herself. "I think of myself as quite a shy person," she says. "So it's actually easier to be myself on Facebook because you can edit what you want to say, take your time; you don't feel awkward. I definitely feel more confident online more like the self I know I really am, beneath the shyness."

These new communications technologies, Olivia says, are "an enhancement, an enrichment actually. They bring people even closer, in fact, without replacing anything. We're not socially abnormal. Look at us!" And the experts seem to back that up. Valkenburg says: "Our research gives no reason at present for concern about the social consequences of online communication but it's early days. What if the constant self-confirmation teens experience online turns into excessive self-esteem, or narcissism? We don't know yet."

Lenhart puts it another way. "Our research shows face-to-face time between teenagers hasn't changed over the past five years. Technology has simply added another layer on top. Yes, you can find studies that suggest online networking can be bad for you. But there are just as many that show the opposite."

We should, she suggests, "Step back. The telephone, the car, the television they all, in their time, changed the way teens relate to each other, and to other people, quite radically. And how did their parents respond? With the same kind of wailing and gnashing of teeth we're doing now. These technologies change lives, absolutely. But it's a generational thing."

Teenagers: how addicted to Facebook are you? How much do you use technology and what for? Post below or email g2feedback@guardian.co.uk

Why is a company that insists its partners will announce a slew of tablets and slates asking to find out how Apple users interact with theirs?

Here's an intriguing one: Microsoft User Research wants to find out more about iPad users - in detail, via a two-hour, in-depth study that it's going to carry out at its campus over the next week or so.

Remarkably, the company openly advertised its desire to connect with iPad owners "for an upcoming study to get feedback" on a Facebook page - though within hours of going up, the page was shut down.

Mistake, or was the quota filled rapidly enough to satisfy everything that the company wanted?

Given that it shut down its Courier project, which to some had looked like a viable (or at least interesting) alternative to the iPad, and that HP is reported to have shifted away from Windows 7 for its tablet/slate offering to its newly-acquired Palm OS (though a slide on Steve Ballmer's presentation the other day suggested that HP is back in the Windows fold for tablets/slates: we shall see), this doesn't look promising.

Why? Because if Microsoft has to study how people use the iPad at this juncture, it is going to take it a very long time - six months? Nine months? - to embed whatever it learns into software. Then that software has to go out to the hardware manufacturers, who have to test it against their prototypes, refine, tweak... and then get out to market.

Obviously, we'd love to hear from any readers who are based up in Redmond and have been accepted for the study. What did they want to know? What did they test? Tell us everything, by email (charles.arthur@guardian.co.uk is a good one).

And if you were at Microsoft User Research, what lessons would you be looking to learn from the iPad?

Celebrity nutritionist Gillian McKeith is embroiled in an online identity crisis as her spat with Bad Science writer Ben Goldacre hots up

Oh Gillian.

Gillian, Gillian, Gillian.

An almighty brouhaha has arisen over on Twitter. And it appears we could yet be at the calm before the storm. Here's the story (for the history see here):

Gillian McKeith, of You Are What You Eat fame, appears to have taken umbridge umbrage at a relatively innocuous tweet from Rachel E Moody:

McKeith, currently promoting ahem a new book, was incensed or at least the person operating what has previously been described as her official Twitter feed was. Scienceblogs caught the reaction before the angry missives were taken down:

Note the word "lies" in reference to Ben Goldacre's Bad Science. Enter Mr Goldacre, who tweeted: "hi @gillianmckeith, i'm writing a piece about you libelling me in the context of #libelreform, can you pls contact ben@badscience.net thnks". UPDATE: Goldacre later said he regards McKeith's comment as "a very serious and undefendable defamation".

And that's when the whole situation turned plain weird. Evolving miraculously into third-person mode just days after a first-person verification the McKeith feed sought to take apart those questioning her qualifications.

But it wasn't long before the collection of McKeith tweets were taken down, replaced with an odd volte face: "Do you actually believe this is real twitter site for the GM?" Er, yes? In large part because it was linked from your official website:

As it stands, McKeith is trending alongside Raoul Moat and Thierry Henry. As with everything on the internet, trending topics can't be deleted so how do you solve a PR problem like McKeith?

Experiments like 'Please Rob Me' indicate that what people reveal via location-sharing apps could potentially be harmful to them - and survey finds concerns among users

More than half of people with geolocation-capable mobile devices worry about "loss of privacy" from using their location-sharing features, a survey has found - even though location-sharing apps such as FourSquare and Gowalla have millions of users checking in every day.

Among UK respondents, 52% said they were "very or extremely concerned" about loss of privacy from using location-sharing applications - even though the same proportion said that they geotag photos, indicating where they were taken, when uploading them to the internet.

The survey, commissioned by security company Webroot, interviewed 1,500 owners of devices with geolocation capabilities, including 624 people in the UK.

Yet other data shows that there are more than 1m lonely hearts now looking for location-based love via an iPhone application, and touching two million users checking-in with Foursquare, sharing whereabouts is the social currency du jour.

But that can be risky, as a trio of developers showed earlier this year, grabbing the headlines when they launched Please Rob Me, a live stream of people sharing their location on Twitter, the site playing on the fact these people were out of their homes. After doing what it set out to do - bring attention to the risk associated with location sharing - the stream was turned off.

Yet FourSquare and Gowalla have continued their upward trajectory of users, investors and commercial partners, such as Dominos Pizza, the Huffington Post, MTV and the Wall Street Journal.

But according to David Bennett, director for Webroot in Europe, the Middle East and Africa, "It's not about securing the hardware anymore, it's about securing the person as mobile internet-connected devices become widespread." He reiterates the challenges associated with attitudes towards publishing personal information online: "If you look over the last year, it takes about a year for people to be educated about putting stuff on Facebook - I think it'll take that same amount of time for geolocation applications."

This, Bennett says, gets to the nub of the concern: "A lot of people don't necessarily know what they do or what the implications are of these services. Of the half that thought there was a problem, how many people know that the pictures they're taking can be geotagged? Say if you move into a new house, and you say 'Here's a picture of my house', you then take a picture of you and your family on holiday - this is where cybercrime really expands. What's to stop a certain segment of the marketplace burgling your house? That's the challenge as we go forward."

"I think it's the new version of the telephone directory," Bennett says of the presence of food chains on Foursquare. "Can you be sure the company you're interacting with is really the company? That's one of the biggest challenges. when you rang them up you knew it was them - if it's online how can you be sure? But that's the way the business marketplace is going to go - the next generation of bringing people to the doorstep."

And to the doorstep goods and services will come. Skout is a location-based "social dating application" that connects singletons within metres or miles of your exact location. Last week Skout welcomed both profitability and its one millionth user. But news like this is anathema to the cause of "securing the person". Bennett continues the refrain: "When you're online it's so easy to pretend to be someone you're not. Everyone's hidden behind the keyboard if you start going into some of these dating areas.

"There are certain parts of our information that should always be private. It comes down to people understanding what they're doing."

The research

Webroot commissioned a survey of 1,645 social network users (including 624 UK-based) who own geolocation-ready mobile devices on June 7 and June 8 2010.
- 39% (around 600 of the sample) of mobile device users use location-tracking applications on their mobile phone
73% of those use a "geo-tracking application" to do so
Of this 73%, more than a quarter used location-based services to share their whereabouts with "strangers" and 14% use them to meet new people
55% of respondents said they worry over loss of privacy incurred from using geolocation data
One in 11 respondents have used geolocation applications to meet a stranger, either digitally or in person. This is predominantly within the 18-29 age group
64% have accepted a friend request from a stranger
41% are "aware or extremely concerned" about letting "potential burglars know when they are not at home"
In the UK, 46% of women are "highly concerned" about "letting a stalker know where they are," compared to 27% of men
52% of UK respondents tag their whereabouts in a photograph online
In the past year, 30% of UK respondents have shared their geographical location with "people other than their friends"

On this week's podcast, we'll be finding out more about Facebook's new safety features for under-age users: some are calling it a "panic button", but the social networking service says it's not.

A web designer-cum-wood pellet distributor who says a previous contract entitles him to 84% of the company - and Facebook can't get more venture funding until the case is settled. By Jemima Kiss

Facebook is in court to defend yet another claim to ownership, this time from a web designer cum wood pellet distributor who says a previous contract entitles him to 84% of the company.

Filed in the Supreme Court in New York's Allegany County last month, the lawsuit details how Paul Ceglia signed a contract with Facebook in April 2003 to design and develop the website TheFacebook.com for an agreed $1,000 ( 665) fee and a 50% stake in the site.

The contract stipulated, Ceglia claims, a further 1% stake for each day until the site was finished on 4 February 2004. Facebook is valued at an estimated $6.5bn, so an 84% share would be worth around $5.46bn.

Following Ceglia's lawsuit, acting New York Supreme Court justice Thomas Brown issued a temporary restraining order that blocks Facebook from transfering assets. That means that the company cannot raise any more venture capital by selling shares until that order is lifted. The case has now transferred to a federal court and Facebook is trying to have it annulled.

Facebook dimissed the case as "frivolous" and "outlandish", said it will fight it vigorously and pointed out that a lawsuit over a contract broken in 2003 is "almost certainly barred" by the statute of limitation.

There are a number of reasons that success for Ceglia sounds unlikely not least waiting until the site reaches 500 million global users before bringing his case, waiting until the outcome of the (successful) Winklevoss claim and the rather bizarre sidenote that a restraining order was granted against him in 2009 by an attorney who alleged Ceglia had defrauded customers of his wood-pellet fuel business to the tune of $200,000.

But imagine, for a minute, that Ceglia succeeded, and moved in to take 84% of Facebook. We might have a new entrant in the MediaGuardian 100...

Three computer experts reveal how their office lives compare with the TV comedy

Wondered what the real-life counterparts of Jen, Moss and Roy make of Graham Linehan's much-loved sitcom? We asked three tech-heads to tell us what they think.

IT project manager Shaheen, 38, is married with two children and lives in Cheshire. Technical architect Harry, 34, is separated with two children and works in Greater Manchester. Account manager Bob, 31, works for a major IT outsourcing firm in Greater Manchester.

Do people like Moss, Jen and Roy really exist?

Shaheen: People like Jen exist there's one in our department, who was hired to translate between the geeks and the management but she doesn't have a clue what she's doing.

Harry: People like Moss and Roy exist less and less, because the competencies you need tend to mean you're multi-skilled, so you can't just ignore people and sit in front of a screen all day.

Bob: The Jen figures aren't exclusively female. There are plenty of men with top jobs in project managing who don't know the first thing about IT.

Can you spot IT people by their clothes?

Bob: Yes. One guy I work with has a utility belt. It's got his PDA, his personal GPS unit and multiple phones on it. He's got his pants dead short, and he never speaks to anyone.

Harry: T-shirts [Harry shows his Darth Vader T-shirt with the caption: "I Am Your Father"].

Shaheen: I think it's generally a guy thing. Though I have been known to wear the occasional rock T-shirt to the office.

Are IT people treated with contempt and hidden in a basement, as they are in the show?

Shaheen: When I've worked on site, IT people have a godlike status. I've had factory foreman shouting at staff, telling them what they can and can't do, based on my word and whim, so I've seen the opposite.

Harry: It's quite central to The IT Crowd that the department is stuffed away somewhere, and that isn't the way we work. Going back a few years, it was like that, and people used to complain that we were obnoxious, a bit prickly, difficult to talk to when they needed something sorted out. Now, it's moved, and it's very much integrated with the rest of the business.

Bob: More and more businesses are getting rid of their IT departments. It's all about self service now, and any technical needs are outsourced. In that respect, I think the show is documenting a dying culture. I think it was dying even when the show started.

Do IT people lack social skills?

Harry: There's quite a few stereotypical geeks in our department, but only one or two with no social skills.

Shaheen: One guy I worked with built a wall of box files around the edges of his desk so that people wouldn't look at him. I think IT does attract a few obsessive, slightly odd personalities, definitely.

Bob: Less and less, though what's happening to these people is perhaps a mystery. I think a lot of them have been forced to take on more business-focused roles.

Are IT people particularly into geeky pursuits?

Bob: There's people in the office who spend 20-30 hours a week on Warcraft. But I think you'd find people like that in the rest of the male population.

Harry: Guys on the coding team go home and work on open source stuff in their spare time, and I must confess, one of my hobbies is to build virtual machines when I'm not at work.

Shaheen: I think the only way I can relate to a lot of the stuff that goes on is that I'm into metal and rock that subculture is massive among IT types.

Does the IT sector respect diversity?

Bob: There is sexism in IT. There are very few women in technical roles.

Harry: Where I work, there is a representative number of ethnic minorities and two women on the configuration team.

Shaheen: I've sat in meetings where senior consultants said: "She's not going to do anything" and "She doesn't know about it." I took it at the time, because I was new, but sexism is a very real thing in IT.

Does the advice "turn it on and off" really work?

Bob: With surprising regularity. From an outsider's point of view, that is everything that we do.

Harry: It solves 80% of problems. You've got to know when to switch it on and off. Switch it off, wait 10 seconds, then switch it on, that's the trick.

Shaheen: It does, but IT people dress it up. They'll say, "Have you given it a service reboot?" There's quite a few euphemisms they've developed because it's often effective. Like a "power recycling", "refresh" and things like that.

Blogging is not on the way out it's just that other social media have taken over many of its functions

A report last month in the Economist tells us that "blogging is dying" as more and more bloggers abandon the form for its cousins: the tweet, the Facebook Wall, the Digg.

Do a search-and-replace on "blog" and you could rewrite the coverage as evidence of the death of television, novels, short stories, poetry, live theatre, musicals, or any of the hundreds of the other media that went from breathless ascendancy to merely another tile in the mosaic.

Of course, none of those media are dead, and neither is blogging. Instead, what's happened is that they've been succeeded by new forms that share some of their characteristics, and these new forms have peeled away all the stories that suit them best.

When all we had was the stage, every performance was a play. When we got films, a great lot of these stories moved to the screen, where they'd always belonged (they'd been squeezed onto a stage because there was no alternative). When TV came along, those stories that were better suited to the small screen were peeled away from the cinema and relocated to the telly. When YouTube came along, it liberated all those stories that wanted to be 3-8 minutes long, not a 22-minute sitcom or a 48-minute drama. And so on.

What's left behind at each turn isn't less, but more: the stories we tell on the stage today are there not because they must be, but because they're better suited to the stage than they are to any other platform we know about. This is wonderful for all concerned the audience numbers might be smaller, but the form is much, much better.

When blogging was the easiest, most prominent way to produce short, informal, thinking-aloud pieces for the net, we all blogged. Now that we have Twitter, social media platforms and all the other tools that continue to emerge, many of us are finding that the material we used to save for our blogs has a better home somewhere else. And some of us are discovering that we weren't bloggers after all but blogging was good enough until something more suited to us came along.

I still blog 10-15 items a day, just as I've done for 10 years now on Boing Boing. But I also tweet and retweet 30-50 times a day. Almost all of that material is stuff that wouldn't be a good fit for the blog material I just wouldn't have published at all before Twitter came along. But a few of those tweets might have been stretched into a blogpost in years gone by, and now they can live as a short thought.

For me, the great attraction of all this is that preparing material for public consumption forces me to clarify it in my own mind. I don't really know it until I write it. Thus the more media I have at my disposal, the more ways there are for me to work out my own ideas.

Science fiction writer Bruce Sterling says: "The future composts the past." There's even a law to describe this, Riepl's Law which says "new, further developed types of media never replace the existing modes of media and their usage patterns. Instead, a convergence takes place in their field, leading to a different way and field of use for these older forms."

That was coined in 1913 by Wolfgang Riepl. It's as true now as it was then.

Digital publishing deals locking writers in for the duration of copyright risk damaging industry, says Society of Authors chair

The chair of the Society of Authors, Tom Holland, has hit out at publishers' attempt to seize control over electronic rights, calling ebook deals that lock authors in for the duration of copyright "not remotely fair".

Speaking at the Romantic Novelists' Association's annual conference last week, Holland urged authors to push for ebook royalties that are "considerably higher" than the standard of around 25%. Although Holland said the market for ebooks is only about 1% of the total UK market, it is "growing fast" and the Society of Authors believes that, given publishers will eventually have much lower warehousing and distribution costs for ebooks, royalties should be divided 50/50.

"Most publishers are insisting they should control ebook rights and this will be written into standard contracts. I think it's an entirely reasonable position to take, so long as the royalties and returns on ebooks are fair and proper and reasonable. If they are not, I suspect we may well find very big-name authors, such as JK Rowling or Dan Brown, will go their own way," said Holland. "It's a danger publishers need to recognise and a danger for writers as well. If JK Rowling controls her own ebook rights [then] there's less money for her publisher to invest in new authors. We could face a situation of very big-name authors pulling the ladder up after them [and] we have a stake in seeing a healthy publishing industry."

Although publishers "are inclined to dismiss the argument that costs are reduced on ebooks", Holland said: "Once a system has been set up, publishers won't be paying for warehousing, distribution and printing, and we have to ask ourselves what are they spending the money on?

"We accept that publishers have been investing heavily in digital infrastructure and at the moment they are losing money on ebooks because sales are so low. I can sort of understand their reservations over higher royalties at the moment, but nevertheless a contract that lasts for the duration of copyright is a hugely long time. Publishers in negotiations with Amazon, or whoever, say they want two-year contracts because there's such flux, but at the same time are asking authors for the duration of copyright. It has to be wrong it's not remotely fair," he said.

"Twenty-five per cent might be reasonable as the infrastructure's set up but only for two years. The risk if we don't do that is that the rate will essentially be set in concrete, it will freeze and be taken as the norm, not just for two to three years but for two to three decades. If we don't fight it now, we will lose our chance to present and make our case, and that will be it."

Katie Fforde, bestselling novelist and chair of the Romantic Novelists' Association, agreed that a 25% ebook royalty "would be perfectly fair if it was for two years, or a limited period, and then could be renegotiated". "We don't want to go on and on paying for the set-up costs," she said. "I think a 50/50 split is greedy, but if you don't ask you don't get, and I imagine that might raise the negotiations."

The Samuel Johnson prize-winning historian Antony Beevor believes the Society of Authors is "absolutely right". "To begin with, publishers were trying to set a royalty of a lot less than 25%, they were trying to get around 12.5-15%. Fortunately the agents have taken a pretty strong line and so has the Society of Authors, and I fully support it," he said. "Publishers are suffering badly themselves [at the moment] but it's a bit like Tesco and the farmers the author as the producer will be squeezed the most."

The Flip range of camcorders puts 8GB of film time in your pocket. But where should you go to get the best price?

Video cameras have caught up with digital cameras when it comes to ease of use and reduced size, and the latest Flip range has taken amateur movie making by storm.

Fitting easily into your pocket or handbag and weighing only 170g, the miniature size does not impact on quality: the UltraHD range lets you shoot stunning 720p video that will look crisp and clear on your HDTV, even in low-light conditions.

There is a "flip out" USB arm that directly connects to your computer and instantly launches FlipShare. This software allows you to upload your footage instantly on to YouTube or MySpace. Its intuitive drag-and-drop interface also offers organising, emailing and editing options covering everything from creating custom movies to sharing your favourite snapshots.

Below are the best prices available at the time of publishing for a black Flip Video Ultra High Definition Camcorder with 8GB Memory (RRP 159.99). It films approximately two hours of HD video, perfect to capture those great holiday moments. Readers who have found better deals should post the details below.

Twitter finally explains new EarlyBird promotional account to distribute exclusive offers to users

Despite reeling in $160m in venture capital funding and worth an estimated $1bn, Twitter is still on the hunt for sustainable revenue sources to support the company.

Early indications on Promoted Trends and Promoted Tweets appear to have been successful, and are part of a larger strategy to avoid paid accounts yet gain financial security.

After what seems like a lifetime, the company has now officially announced EarlyBird, which aims to inform users of special promotions that are unique to Twitter and the account. Selected advertisers will pay to distribute offers to the thousands of users present on the network, although none of these has yet been named. The offers will be time sensitive, so fast action will be needed to catch that particular worm.

EarlyBird functions in the same way as a normal Twitter account for the offers to appear in your follow feed. Unlike Promoted Trends, however, they do not appear automatically on your front page and it is an opt-in service, as opposed to the opt-out follow that had been mooted. EarlyBird tweets can also be retweeted to pass them onto your followers.

What's the catch? Initially, EarlyBird offers will be US-centric, although Twitter has said this will likely change: "We're starting with US-wide offers but will explore location-based deals in the future."

The opportunity for EarlyBird to go viral is huge, with offers potentially spreading around like internet like wildfire if they are deemed worthy enough. As I type, the account has 9,545 followers, something that will need to multiply infinitely for the scheme to be successful. Thanks to the joys of trends and retweeting, this seems likely. Assuming the followers flood in, Twitter will be closer to long-term sustainability.

Lucy Cooke's Vimeo film is just what the Sheffield Doc/Fest judges are looking for

Within a week of visiting the world's only sloth orphanage in Costa Rica last year, Lucy Cooke had made a rough-and-ready 90-second clip that was being watched by more than 160,000 people a day. Her decision to "go and shoot a bunch of sloths" put her at the epicentre of online viral video.

With her original footage still attracting thousands of eyeballs daily, Cooke is now in final talks with broadcasters about producing a full-length documentary. "I posted the 90-second video on my Vimeo site and very quickly it was favourited [sic] and pushed by Vimeo staff," she explains. "I then put the word out via my personal Facebook page and also my Amphibian Avenger Facebook and Twitter feeds. The video was then tweeted and retweeted by a few key friends who have a lot of fans."

Cooke's clip really took off after being tweeted by Jonathan Ross and Stephen Fry."It was watched by 1 million people in the first 10 days," she says. "The video has now been watched by over 2 million people if you include YouTube and all the people who ripped it and posted it as their own work on YouTube and other sites."

Cooke gained insight into marketing video last year at a workshop by the digital media organisation Crossover, which will host public workshops around the UK in the run-up to the Sheffield Doc/Fest in November. Cooke is just the kind of person that this year's competition, which is supported by MediaGuardian, is hoping to attract. Entries for the Digital Revolutions category open today.

Says the Doc/Fest director, Heather Croall: "This time we're taking the computer age into a new world. We're going to get people to put their video up on YouTube or Vimeo and really get creative in the digital landscape. As well as producing a great three-minute video, judges will be looking strongly at how film-makers have gone about engaging their audience and building a community around their film."

BCS, The Chartered Institute for IT, is providing a cash prize of 10,000 to be won by a non-professional film-maker at Doc/Fest who can deliver more than just clever video editing.

And Cooke's advice to this year's entrants? "Choose a popular subject look online at what videos and what subjects go viral," she says. "My video is essentially strong, cute and funny animals cut to music one of the most popular genres of viral.

"Look for internet sites which collect videos like yours and send them your link asking them to plug it. Definitely use Twitter and Facebook. Half the job is making something good, the other half is working the marketing of it."
