Great question, would be great to have a general "HN for other professions" thread!

One that I can share is econjobrumors.com, but I also have to strongly warn about it. It's a forum for econ PhD students and academics to discuss the academic job market, but unfortunately, due to its no-sign-up anonymous posting feature and looser moderation policy than HN, it's been taken over to some extent by right-wing trolls - it's even made the news at one point about how it might drive minorities and women out of the profession, that's how bad it was (is?). But last time I checked (a few years ago) it was still very active and even used by young academics from other disciplines (especially math) to discuss their job market, and I saw several "Is there an EJMR for Y?" posts, indicative that there were useful signals for people on the academic job market between all the noise.
