I've had to pare down my podcast listening since I don't drive as much as I used to and usually don't get into listening at home. I have a few categories that I listen to a couple of podcasts each in. These should all be easily found in any podcast directory.
War Rocket Ajax
Jay and Miles X-plain the X-Men
I also used to listen to Life Leave Me Alone but their feed address changed and I haven't gotten around to catching back up yet.
Welcome to Night Vale
Thrilling Adventure Hour
Campaign (Getting into this last year is the reason I'm behind on everything else except for WRA and Jay and Miles)
Adventure Zone (just starting this one, seems good and I hear it gets better)
Making (I'm way behind on both of these, hopefully they're still updating):
Misc: My Brother, My Brother, and Me
