So I'm new to this whole podcast thing, I'm just playing with iTunes a bit (no I don't have an iPod or anything, but my fiancee does and has iTunes on her iBook). So far I've enjoyed the Cheap-Ass Gamers cast, and to a less extent, the Poweruser.tv cast.
CAG iTunes Podcast Link (Tokyo Game Show)PowerUser.tv you can find the cast's off this RSS, use it as a "Live Bookmark" or put it into iTunes, or just search on iTunes for Poweruser.tv.
RSSI listened to the latter one because it has a regular contributer named Tom Chick who is from a gaming site, which has a forum I frequent, called
Quarter to Three (as in how late you stay up playing good games).
