AmigoFish has a huge collection of podcasts, both audio and video. There you can rate your favorite podcasts, and when you reach a certain number (only a few, in my opinion) AmigoFish will automatically give you ratings for other podcasts based on your ratings preferences. The rating is expressed in stars, with a total of five stars. User ratings are shown with yellow stars, and AmigoFish automatic ratings are shown with red stars.
