Chris Messina and others are organizing BAR Camp this weekend at Socialtext‘s offices in Palo Alto. It’s a grassroots gathering of techies doing cool stuff that’s open to all, an open alternative to O’Reilly’s invitation-only FOO Camp, which is happening the same weekend in Sebastopol. Even though it was literally organized this week, a lot of cool folks have already signed up, and it looks like it’s going to be a blast. Hope to see you there!    (JOC)
