Music and technology's happy union (see SXSW, Pandora, MySpace) is impressing us once again for Outside Lands, which is shaping up to be quite the tech-fest. Pick which shows you want to see and compare with your Facebook friends with Ranger Dave's Magic Scheduler, tweet your reactions and tap into festival buzz with the hash tag #crowdfire (we're definitely curious to see what goes down at the M.I.A show) and upload your videos and photos to Crowdfire and 7x7's oh-so-music-and-tech-savvy office mates, Spin Earth.  There's even a (free!) Outside Lands iPhone app, which is potentially a day-saver: an interactive map of Golden Gate Park and updates on event news and weather.
