Talk on techno-utopianism

Brian Dear points out a talk by Fred Turner of the Stanford Department of Communication entitled 'From Counterculture to Cyberculture: How The Whole Earth Catalog Brought Us "Virtual Community"' (abstract, Windows Media stream). I haven't watched the talk (the stream isn't Mac-friendly) but it sounds interesting and apparently kicks off by analysing Wired's 1997 Long Boom article.
