Podcasting

Do any of you listen to podcasts? I tend to listen to a lot of them, with a handful I go back to regularly. There's one of Comic Geek Speak on Crisis on Infinite Earths that is very good, and very in depth. Well worth the time.
Most of them, though, aren't very good. I was listening to one this morning which was a book recommendation podcast about The Killing Joke. One of the two "reviewers" didn't even know Alan Moore had written superhero books, beyond Watchmen. I just find a lack of understanding the basics a bit annoying. Then there are ones where people think they're funny or witty, and they're not. Or where they try hard to be profound or intelligent.
Anyway, do you have any recommendations? Any subject is fine, although comics is board-related.

Well, I guess I should recommend the regular Outpost Skaro Doctor Who podcast, given that a) it's usually pretty good and b) I'm a moderator on the Outpost Skaro forum...

I like the one Chris Hardwick does. He's kind of overeager on TV, but in his podcasts he's much more relaxed and asks the people he interviews really great questions. I've never actually listened to any others, though, so I might just not know what is and isn't quality.
