Ask HN: I'm making an app to discuss podcasts – which podcasts would you want?

I made an iOS podcast app with a Reddit-style comment system. It lets you submit recorded voice comments. It's kind of like a book club, but for podcasts.

Here are screenshots: (https://econtalk.club/shots.html) And a little-too-long video demo: (https://www.youtube.com/watch?v=2xC-oxpiKo0)

(I originally made the app just for EconTalk, but I've decided to expand a little.)

I'm only going to start with 3-5 podcasts. One of those will be EconTalk, but I'd like to hear what other shows might be good for discussion.

I will also be doing a private beta soon. It will probably be between 20-30 users to keep things tight-knit. Apply here if you are interested: (https://docs.google.com/forms/d/e/1FAIpQLScHlg-Jdkl-RHLRO9fHMY0qV-KPyKwk42QXqguhFY5mKSmc_Q/viewform)
