Really been sitting on the idea of podcast recommendations! The big "players" aren't providing any recommendation and maybe they will one day. I believe there is large enough market for a recommendation engine for podcasts!
Most of todays word of mouth is - check out this podcast ______
For me it should be more like - check out episode 124 of this podcast about X.
There are tons of podcasts out there, and we don't have infinite time - but there is a lot of content that a lot of us are missing. Also there are podcast creators that aren't getting the spotlight that they deserve.
You either make a general large netflix for podcast or you niche down to categories and recommend that way.
