Check out the Burning Man Webcast, which, while entertaining you with aural niceties care of 94.5 BMIR, will broadcast the entire festival live 24/7 from the Playa. Whether pro or con Burning Man, you should watch it. The webcast will show you how the entire city comes together in just one week. Fascinating stuff, actually.
For those of you lucky enough to escape the daily rigmarole of life (and can afford ticket prices) and plan on heading to Burning Man for the first time, read SFist's wildly helpful Burner Scribes Bestow Burning Man Tips For Rookies.
