Show HN: Search Podcasts by Guest

Hey Hacker News,

Problem: I often hear someone on one podcast and want more, but there's not an easy way to find them elsewhere.

Until now.

Podda allows you to search podcasts by guest, and also receive a notification whenever a person you like gets on a new podcast.

I just coded this today in ~5 hours, and all feedback is welcome.

Question: right now I only list episodes a guest appeared on. Should I also list podcasts that a guest hosts?
