Mr Brown is the only local podcast I know. Its funny, but listening to 3 guys talking with no topic in particular, is really not my thing. Mr Brown, you seriously need to stick to a few topics per podcast, and try not to cut off your podcast abruptly in the end. But Mr Brown podcast will only get better, I can be sure of it.
In anycase, the following is a rougues gallery of my favourites:
Daily Source Code
Dawn and Drew Show
Keith and the Girl
Jump Cut radio
Not a favourite, but I'll put a link here, for kicks.
