BBC on Podcasts
BBC has a fascinating and engaging radio show online about all kinds of alternative radio, including podcasting. They do the gamut, CB radio, pirate radio, podcasts, examining "how supergeeks and superfreaks will find any means possible to get themselves heard over the airwaves." I have listened to shows about podcasts and listened to podcasts but I was really entertained by how they pull together and give time to a group of podcasters, allowing you to listen to their shows and hear what they have to say.
Worth listening to if only for the Scottish accents...and to hear Dave Taylor explain (with a shout out to Adam Curry) why he doesn't like podcasts.
