A large Podcast Directory

I am actually digging through some older resources and sometimes I do find something remarkable. Sometimes this makes me wonder as I am permanently looking for good services. In this case I found a large and very active podcast directory with thousands of podcasts, which is frequently adding new podcasts. The directory I had never heard about before is Podcast Zoom. There is a well assorted directory at the homepage and the search engine is working fine. Podcasters may add their podcasts.
