I noticed following things about Yahoo! Podcasts
- Doesn’t provided RSS (Media RSS) feeds for categories/search. RSS feeds available for “My subscriptions” only.
- Listening experience is bad because they are using Window Media Player or Quick-Time in popup :). Why not Adobe Flash Player for MP3 files, most of files are MP3?
I hope, they also provide RSS feeds for categories and search. Then I can use Yahoo! Podcasts more often. Second point is not important, I am not sure how many people listen podcasts online.
