A simple introduction to Web 2.0

Although I occasionally find some of its political opinions infuriating, I have a lot of respect for The Guardian, the quality newspaper favoured by the UK’s upper-middle, skinny latte and pancetta class.
It has an enlightened attitude to online availability. At a recent conference, a speaker from the Guardian’s website explained that they are a favourite of bloggers because they keep their articles permanently online and (crucially) free.
In my opinion, the Guardian Unlimited is the best of all the the UK newspaper websites. It sometimes includes some fascinating video, like this 5-minute overview of Web 2.0 from its technology section.
In this film, founders of some of the big sites of the moment such as Wikipedia, Flickr and del.ici.ous (all sites I regularly use) discuss the second-generation internet. If you’re already familiar with the subject, then you probably won’t find any revelations here, but the film is a good intro to those who are confused by the plethora of new big web players and how they are changing the online world.
