I just added another podcast (or 'netcast') to my playlist: Cranky Geeks with John C. Dvorak. I kept forgetting that I wanted to catch his show, and Thing 13 reminded me to go get it.
I do wish there was a better podcast directory out there to find feeds. Performing my normal Google-Fu, I found a few more podcast rating/directory sites out there, but keep on going back to iTunes. A close second to the nice interface iTunes has would probably be ODEO.
Each of the 4 sites I visited have different rating systems, and different 'Top' lists of specific genre's of podcasts to download. I suspect that the iTunes list is a bit more well traveled than the others out there, so I think that's the one I'll stick with.
