Michael has notes and video from Jimmy Wales's talk at NYU tonight; the founder of Wikipedia focused on one of his new venutres, Wikia, which offers free hosting for specialized, open wikis:
Given the audiences familiarity with Wikipedia, Wales skipped most of his prepared speech on that and after he gave a brief background on open source software, how it works, and the fact that you can be commercially successful doing and using it, he spent most of his time talking about Wikia.
(Thanks, Michael!)
