The first podcast I listened to was the series that Ricky Gervais, Steve Merchant and Karl Pilkington and did at the beginning of the year. Really funny stuff, but then they started charging for it, and, guess what, I stopped listening. Not sure if they're even doing them anymore. Probably not. Track the free ones down, though, if you're wanting a laugh or two.
Lately I've been listening to the 1UP Yours podcasts
. Sounds dirty, but really it's just a bunch of dudes talking about video games. Pretty good listen, if you're interested at all in the new games and systems coming out in a couple months.
And speaking of video game podcasts, a friend of mine always listens to Major Nelson's podcasts
. However, it seems to be more XBox 360-centric, and since I don't have a 360 at the moment, I haven't bothered listening to that one yet. I'm sure that once I get a 360, I'll check it out.
As far as Star Wars podcasts go, I've listened to SWAN a couple of times. It's okay, I guess, but I don't know--I think it's way too hardcore "STAR WARS COLLECTING!!!" for me.
And I've listened to Adam Pawlus' and TF.N's podcasts. . . once
