I just got back from RailsConf in Portland. It was really fun to be a designer among a sea of programmers. I spent a lot of time talking to programmers about what designers do on a Rails team and how we should work together. A number of those ideas worked their way into an interview with Geoffrey Grosenbach of PeepCode. Listen to the podcast at Rails Podcast.

UPDATE: Here are some quick video interviews with Ryan, Jeremy, and David from RailsConf 2008.
