They might have a topical directory of podcasts, but if I click on what looks like a topic name nothing happens.
They have their own podcast production studio, which you can rent by the hour and presumably get help producing your show.
They offer podcast hosting services.
But I'm very under-impressed by the presentation on the site. As I said, they have what looks like topic names, but clicking on them doesn't do anything. The show listings are also lame. An interesting thing is the show listing page can have a custom look, I suppose so that a given podcaster can have their show listing looking like the way they want it to look. That's a nice touch.
