I listen to Save Against Frostbite occasionally. They're okay, but honestly I think they try too hard to be edgy with their "yeah, we went there" moments. I did enter in their logo contest earlier this month, though.
As for podcasts, I'm not going to rate them 1-10, but I will give the 10 I listen to most often:
- Bear Swarm! Podcast
- Brilliant Gameologists
- Fear the Boot
- The Game Master Show
- The Independent Insurgency
- The Podge Cast
- Radio Free Hipster
- RPPR
- RPGMP3 Community Podcast
- Theory From the Closet
I also subscribe to Ask A Ninja, Decoder Ring Theater, Save Against Frostbite, Radio Lab, and IPR's Voice of the Revolution.
I used to listen to Dragons Landing and Geek By Night, but they both haven't had any new content in months.
EDIT: Woohoo, I won the SAF logo contest! Free RPG book, here I come!
