Top 10 articles: Facebook annoys activists, HTML5 to replace Windows apps, and Mac crimeware

Our most popular article this week was the news that Facebook had deleted the user accounts of various anti-cuts and anti-tuition fees groups. Some felt that the action, which took place on 29 April, had been deliberately timed to prevent protests being arranged to spoil the Royal Wedding.

However, the day went ahead without a hitch and just as likely is that Facebook was using the tried and tested trick of burying bad news, knowing that all eyes would be on Kate and Wills (and didn't she just look lovely?).

Also popular was our interview with Microsoft's Paul Cotton, who also co-chairs the W3C HTML5 working group. Cotton told V3.co.uk that HTML5 could soon allow any kind of application to run inside a browser, enabling developers to build software that runs across virtually any platform.

And it looks like Mac users might finally have had their day when it comes to security smugness over their Windows PC counterparts. Danish firm CSIS Security Group warned Apple fans to expect an avalanche of attacks after discovering the first Mac OS X crimeware kit being traded on underground forums.
