utomatic allows you to set up subscriptions for virtually any content linked in RSS feeds: podcasts, videocasts, torrentcasts... Rule of thumb: if it ends in '-cast', you can get it with Automatic.

Most of the podcasts I listen to are actually radio programmes too. Or made by professional broadcasters. (Podcasting is a new mode of distribution, but it's not a new medium.)

Complete list of BBC podcasts.

Blimey, it's a podcast worth listening to.

Grauniad podcasts - they're not doing it by halves. (The more pro podcasts the better, I say. Never been able to stomach the amateur drivellings - radio is just not something lots of folk can do, like writing for weblogs.)

Channel 4 News jump on the podcast bandwagon - the first 'cast is a special report by Jon Snow on cannabis and mental health. (Good stuff - my radio-addict ears cannot bear amateur podcasts, so this will join various BBC feeds in iTunes.)

Ray Bradbury radio play (on a site podcasting vintage Sci-fi radio).

Decent podcast, recently featuring Sister Rosetta Tharpe and "an exploration of Bob Dylan's music on the context of the music that inspired it."

Generate your own personal podcast by bookmarking MP3s you find online at del.icio.us with a specific tag and running the tags's feed through Feedburner with SmartCast. Neat.
