I've been enjoying the Laser Time podcast network a lot lately. They have a bunch of shows. The flagship, Laser Time, is a pop culture list based show where they pick a topic and go through and discuss a bunch of examples from it. Vidjagame Apocalypse does the same thing but with video game topics. Cheap Popcast is their occasional wrestling podcast and the only one I don't listen to. They also have a comic book podcast called Cape Crisis, which shockingly, discusses current comics.
Oh, and I also very much enjoy The Comedy Button. If you've never listened, give their best of 2012 episode a shot to see if you do or do not mesh with their style.
