Trying Odeo

In case you haven't heard from Odeo yet: Odeo is a podcast community somehow comparable to sites like flickr. You can browse podcasts by tag, subsubscribe to them, comment and rate them. Odeo also offers a small application called Odeo Syncr that automatically (if you've configured it that way) downloads new podcasts from your subscriptions or any other podcast that's in your queue and hasn't been downloaded yet.
