this keynote may be the most important speech for culture/technology in 2007: http://www.joystiq.com/2007/03/13/sxsw-joystiq-live-at-the-will-wright-keynote/ That keynote alone is enough to make me want to go to SXSW next year.  I hope to be able to synthesize it and give some thoughts on it later... but there's a LOT there to chew on.  Seriously, give it a read; it's dead on with where culture is going.
