This appears to be more of a blog directory than an podcast network, but I found it listed in a listing of podcast directories. Anyway it's pretty badly implemented and pretty hard to use so I won't say very much.

There is a semi useful topic directory in which the aggregated feeds are arranged. However that is where the semblence of usefulness stops. The listing of feeds is darn near ugly, and the page showing each feed is next to useless.
