What Web 2.0 is?

Recently, I found a few pretty damn good video presentations on “What Web 2.0 is”. First one, is rather obvious and just presents a view on history and trends. Second one is really great, it presents the key elements of social networking in attractive, visual form. Third one is rather short, but has it’s value in remix of a few talks about what Web 2.0 is.

Enjoy Web 2.0 🙂
