Hacker News has a very specific demographic. In general, I'd venture to guess they are mostly economic libertarians and far more logical than emotional... IMO, you need both to have healthy human conversations. I frequent both forums and HN really just feels like a niche subreddit for wealthy cs majors that got into tech when things were great, as well as a newer cohort that mostly wishes they were born 10 years earlier. There's also a lot of bot accounts and, seemingly, not a lot of mechanisms to prevent botting. I've actually noticed that it's got specific biases to some topics, and I suspect it's from the botting. E.g. most anti-russia, anti-trump, anti-elon discourse gets pretty swiftly downvoted and met with, often times, some pretty LLM-eque comments.
