Remixing what web 2.0 implies

Catching up with Twines, I get to a blog called This Is Indexed, where I find this simple but yet effective definition of what web 2.0 means (to Jessica, the author, and many more). I revamped it with Gimp (I’m useless at drawing), and added a 3rd axis. We could add a 4th one: value (i.e. whether more quantity means more quality or more quality comes from selective aggregation…”if the more users, the better the app gets”…can we say the same thing about the social networks we belong to? my own list of contacts?). More axes?
