Shelly from Pathable wrote a great summary of the social software package we put together for Foo. I especially like her description of the collaboration:

we were, individuals from five separate organizations, collaborating to create a fully featured, unique social networking experience for Foo Camp attendees – with only six weeks to piece it all together. This, as much as anything, emphasized for me what a great job O’Reilly has done in creating an environment that generates the level of trust and shared passion that enables this sort of effort to succeed.
