i'm still sorting out the content. right now i'm mostly interested in professionally produced stuff...this makes it like a radio Tivo. unfortunately most radio/TV stations haven't caught the fever yet.
here are podcasts for kcrw. le Show is pretty funny, harry shearer's weekly take on the news.

it would be cool if other stations would make it easier to listen to existing archived programs like this...i guess i'll just keep looking.
