I don't really listen to many podcasts or have many feeds I check. Just stuff like CNN, the drudge retort for news and ARS technica, macrumors, and slashdot for tech stuff plus appshopper where I found this deal at.
I downloaded it since it was free, and there's two major problems.
1. I don't want to have to type in a really long url consisting of numbers and letters and slashes and colons and everything.
2. The interface doesn't feel right. I'm not sure where I go to listen to latest episodes, download episodes, etc..
