Well, niche forums are kinda different when they manage to stay small and niche. Not just HN but car forums, LED forums, etc.
But if they ever include other topics, they risk becoming more mainstream and noisy. Even within adjacent fields (like the various Stacks) it gets pretty bad.
Maybe the trick is to stay within a single small sphere then and not become a general purpose discussion site? And to have a low enough volume of submissions where good moderation is still possible? (Thank you dang and HN staff)
I'm not entirely sure it's about content (while HN is certainly tech-focused, politics, health, philosophy all come up with regularity) or even content moderation, although they both certainly play a part (particularly the moderation around here. Thanks, staff!)
I wonder if it is more to do with the community itself. HN users tend to have very intelligent discussions on pretty much anything, and discourages shitty, unnuanced, one-line takes. This, coupled with a healthy moderation system, makes it hard for the lower quality discussion to break in and override the good stuff.
