We broke up into several groups, picked one out of a handful of Ruby microframeworks, and hacked together a Reddit clone - or, as much as we could build in about an hour. Below are some of the results:
App: Dark Roast
Participants: David Jones, Timothy Barnes, Gentleman Whose Name Remains a Mystery to My Feeble Mind
Participants: Alex Conner, Chris Wingate, Adam Jahn, David Christiansen, David Estes, Miles Sterrett
Participants: Chris Zelenak
Some explanation: Z decided to build his own framework/server that approached the problem in a completely different and interesting way. You should check it out.
