I just started listening to a new podcast about a month ago called FLOSS weekly. It's one that my brother suggested, and I find that I'm really enjoying it.
I'm actually kind of suprised at first that my brother recommended it, I mean he is into technology and all, but not really into the software development side.
After listening to a couple of episodes I've realized why he likes it. It's not a nuts and bolts development podcast (I'd like to find one, was liking the Macbreak-Developer one, but it seems to be floundering) but instead talks at a higher level about Open Source projects and the community.
It's actually got me looking at the whole Open Source concept a little closer and with a different viewpoint.
