I'm a big fan of the .This Week in Science podcast. It's hosted a PhD neuroscientist and her co-host is this funny Adam Corrolla type guy who sells washing machines when he's not on the radio. Great show - good info, but entertaining at the same time.

Well I've just started getting into podcasts. This is because there hasn't been diddly squat available (in my opinion) for new music lately and I needed something new to help me get through mowing the lawn.
I've subscribed to the following thus far. I'm still sitting here sampling podcasts to see if I've picked what I really want at this point in time:
-Queer Eye Hip Tips
-iTunes New Music Tuesday
-iLounge.com (you'd be silly not to!)
-Science Friday (astronomy, etc. fascinates me)
That's what I have thus far. I'm perusing this forum to see if there are others I might want to try... I just wish there was more time in a day to listen. I think this will be like trying to keep up with the barrage of magazines I get every week. Ah, it's tough!
