The FOC podcast is super fun and they end up discussing a few esolangs from the Forty-Four Esolangs book (Entropy, FatFinger). I'm also on a podcast about the book with Sam Arbseman (author of Magic of Code): https://podcasts.apple.com/us/podcast/daniel-temkin-on-esote...

Hello sir! I found out about esoteric.codes from FOC a while ago, have read most of what's on there since. Honestly surprised Steve (or early days with Ivan) never had you as a guest / interviewee. So I'll definitely check this one out. Congrats on what looks like an amazing book, can't wait until I get to read it.

Thank you for bringing an underappreciated corner of computing to people's attention!

Thanks! It's so nice that esolangs are starting to get wider appreciation as a cultural form.
