I think of it as the changes that are making the web a lot cooler and more interesting. It’s users supplying the content: things like social-networking sites like Myspace, information wikis, Youtube, Liveleak, various video streaming, mp3 downloads. Stuff added to and shared on the web by users.

Oh...I thought it had something to do with redoing the internet...in particular, (256)^4 IP addresses aren’t enough to go around...also aren’t the packet routing algorithms nowhere near optimal?
