A Beutiful Video Textual-Visual presentation from DR Wech, about, well, couple of things - text in the digital age, web 2.0 (as in the decoupling of form and content, and about the new age of man-machine relationaships. YouTube - The Machine is Us/ing Us (Final Version)

If you have an extra hour:
A very interesting anthropological study of Youtube, online community, human nature and motivations .
Kinda long, (55 minutes), and a little slow at points, but worth the investment.

oh, yes, and maybe the best of them all, the ever classic Information R/evolution

Enjoy
