Tagging is too unreliable. Is there a search engine that crawls podcasts/videocasts and presents good discovery features for episodes? I'm tired of subscribing to feeds that only once in a while have interesting guests/subjects. There is no way of knowing if listening will involve topics I will be interested, we need some good disruption in podcastig and Spottyfi ain't it. Reading podcasts as text is not a way to go unless the user is hearing impaired. Turning audio into good blogposts with AI and some careful human editing could be good though if done correctly.
