Web 2.0 in 5 Minutes.

Heyho,
yesterday while browsing the web i found a pretty cool video which sort of explains Web 2.0 in less than five minutes.
The cool thing about this video is, that it was actually just a response to a different video, explaining it in 7.5 minutes (or so), but with really talking and explaining stuff. I have to say, i prefer this way of putting it a lot.
The guy is an assistant professor for cultural anthropology, and this subject keeps getting more and more interesting. Reckon i gotta see if i can get me a few books on that topic. :) But anyhow, just watch.
