I have 2 podcasts to share concerning webcomics that may or may not be of interest to you folks... the first one is created by Tom Racine, a card carrying nerd who I used to work with many years ago. He interviews all sorts of cartoonists both print and web based:
The other is hosted by 4 popular webcomic creators who talk about their own webcomic experiences and interview others. They can get off subject for long periods of time, but there are some good nuggets of knowledge in there. These guys wrote the book about webcomic publishing (http://www.pvpstuff.com/howtomawepor.html)and Scott Kurtz (PvP) is moving to the Seattle area soon and may join TAG when he gets here.
