BarCamp returns in DC with its second run. The event has been sold out for weeks, but there is a waiting list on Eventbrite:

BarCamp DC is an ad-hoc unconference and is part of the larger BarCamp movement. While there are topics suggested for discussion, there is no set agenda until everyone gathers. Attendees are required to participate to some degree: either by giving a presentation, demo, etc. or by facilitating a group discussion. Topics are flexible, as well.
