Updated below with review of what happened.

Some geeks dismayed by the closed-door policy of another group of geeks, are doing their own thing. Read Andy Smith’s note here for more. Here’s the gist:

FOO Camp happens every year, it is an invite-only event for tech luminaries hosted in Sebastopol, CA at the O�Reilly headquarters. People camp out, have sessions, and work with other great tech minds to come up with awesome ideas. The problem is the exclusivity: everybody isn�t invited.

Meet BAR Camp, an open, welcoming, once-a-year event for geeks to camp out for a couple days with wifi and smash their brains together. It�s about love and geekery and having a focal point for great ideas, like SHDH more in-tents (GET IT?!), like FOO but open.

Ross Mayfield has more details here.

Update, 8/22: Thanks to Techcrunch for a review of what happened at Day 1, and Day 2 of Bar Camp.

8/23: And Susan Crawford has review of Foo Camp. Via Scoble:

Foocamp tags on Technorati: Foo Camp and foocamp. Tagging really works great for events like these.

Scoble’s blog entries over the weekend are really worth reading, btw, if you’re interesting in getting the buzz on this stuff.
