I've been listening to podcasts since the beginning with Adam Curry's Daily Source Code, and now the No Agenda Show. I also listen to This Week in Tech with Leo Laporte when I can. My job now keeps me in the office daily, where I used to be on the road every day for a sales route, so I don't have much of a commute to listen anymore.
Anyway, that said, I would love to do a GH podcast with some other members, time permitting.
