There is now a video archive on the HASTAC website. A great resource. I particularly recommend the streams from the Electronic Techtonics conference, April 2007. – including “The Social Life of Learning in the Net Age” (John Seely Brown), “Global Interfaces, Intimate Interfaces and the Interface between Art and Technology” (Rebecca Allen) and a panel discussion on “The Foundations and Futures of Digital Humanities”. The quicktime streams seem to work better in Firefox than IE (at least on my computers).
