I am in the middle of a long trip and need something quick and easy to post. So I figured I'd post a list of the podcasts that I like.
Ask An Atheist: Call in show, although they usually just do prepared topics
Culture Wars Radio: I'm new to this one, but he talks about atheism and politics it seems
Godless Bitches: A podcast about feminism and atheism
Reasonable Doubts: Atheist radio show, not really sure how to expand the description on this one :)
The Atheist Experience: public access radio call in show from Austin. These guys are a large part of what inspired me to start this blog
The Non Prophets: Atheist Experience guys talking about atheism without calls
The Adam Carolla Show: Basically a morning radio show in podcast form, except actually funny. Warning, there is no censorship here
Planet Money: They talk about economics in a very simple, easy to understand way. Very well produced program.
Econtalk: More long form economics discussion from a college econ professor. Really interesting but a little dry. I think it is great but I have to be in the right mood for it.
The Weekly Weinersmith: The guy from SMBC talking science with his wife. She studies parasites so that comes of a fair bit...awesome
The Titanium Physicists: A couple physicists explain a difficult physics idea to a non-physicist. I really like the format.
Skeptics Guide to the universe: skepticism and science. My favorite thing they do each episode is "science or fiction" where one guy gives a few science stories and the other people have to guess which story is fake.
Variety? (not sure what to call this category)
This American Life: Great Stories each week
Radiolab: Similar to TAL, not as good but I still like it a lot.
I already have more on my list than I can really keep up with, but if you know of another podcast you really like feel free to add it in the comments.
