In a fit of conference cluelessness dejour, the attendees of SXSW were required to pay $90 to hook up to power. But all's well now since the bloggers there asked, WTF SXSW? I hear cameras are also prohibited, but that hasn't stopped some folks.
Good. Conference freaks, rockon. We'll save you a place on the phone, where you are allowed to tape, take pictures, and plug into your household outlets (cordless only).
