I've been listening lately to The Daily Source Code from Adam Curry (yes, that Adam Curry), and have really enjoyed the format. It's a bit goofy, and really laid back, but has a pretty good vibe to it. Not sure if I totally agree with a lot of the hype that podcasting has generated, but honestly if there is any chance of me doing a radio show again, I think this would be the format I'd release it in. Too bad the RIAA is pretty much against any redistribution of their music in any format without a license, but oh well. Wherever there is a void, something comes along to fill it.
