A friend of mine passed on this great video at YouTube by Michael Wesch (Assistant Professor of Cultural Anthropology, Kansas State university). I also noticed that Alec Saunders has it on his page too, so it looks like this video is making the rounds.
I thought it was simply fantastic. A tip of the hat to Professor Wesch and his team. Enjoy.
(Keep your speakers on).
And then, once it excites you, how about diving into some details of web 2.0 :-)
