Podcast Finder recommends new podcasts based on the listening habits of other people who like your favorite podcast* creators.
(The search is easier if you have JavaScript enabled.)
For now, the podcasts here are hand-curated, as the problem with most other podcast lists online is that the most prominent podcasts often seem to have gotten that way through cheating or the exchange of money. If your favorite podcast isn't here, feel free to email jamidwyer [at] gmail[dot]com.
*I'm using the word podcast to include audio books and comedians. If there's more talking than music, I'm calling it a podcast. **A username is optional -- it's there so your favorites can go into the database to improve future results. You won't be able to access your favorites or your results with your username, but if you'd use the same username (or none) each time you use Podcast Finder, it'll give more accurate results in the future.
