This past Saturday night, YouTube held its YouTube Live event sponsored by Virgin, Flip, Lionsgate and Guitar Hero. The event, broadcast live from Fort Mason Center in San Francisco, included performances from Tay Zonday, will.i.am, Katy Perry, Joe Satriani, Bo Burnham, Michael, Buckley, Lisa Nova, Beardyman and many more. It was a geek fest to end all geek fests. But where was LonelyGirl16? Gary Brolsma? Syncsta (Barbie Girl, What is Love, Numa Numa, Ballroom Blitz Celebrate)? Tron? And all those other YouTube geeks?
