Web 2.0 : what is it, my own take

So many definitions have been made about web 2.0, what's the motivation of giving another one?
Well, as presumptuous as it is, I think I have the right definition of web 2.0 :)

Web 2.0 stands for "there is more to the web than web 1.0"

This definition is why there are many views of what the web 2.0 is.

• For the marketers, web 2.0 will be all about having turning a publishing system into a media.
• For the designer guys, web 2.0 will be about having snappy GUI through AJAX web pages.
• For the developpers, it will be all about rendering the web programmable
• etc...

I told you, it's all structural ...
