You don't know foo, and niether do I, so I did a little digging to uncover what all the foo is about.
Foo Camp is an annual invite-only unconference hosted by O'Reilly, complete with a totally-Tim-hosted Foo Bar. This year the conference was held June 22-24 and saw 250 talented participants who do interesting work in fields like web services, data visualization and search, open source programming, computer security, hardware hacking, GPS, alternative energy, and other fields that can be described as 'emerging technologies'.
Much of the agenda is determined by the participants, who are encouraged to show up prepared to lead or participate in a session, ask interesting questions, or show off what they've been working on.
All this makes me think...
