The idea: Get 200 or so smart folks with a lot in common together in one place at one time, let them pitch tents, toss in a Wi-Fi network, and see what happens. Turns out, quite a lot.
According to CNN, O'Reilly & Associate setup camp [Camp Foo] in northern California and invited some of the smartest geeks in the area to join them for some marshmallows :)
We should do something like that up here in Ontario one weekend, could be fun -- lots of smart geeks in Ontario, or so I'm told.
