Well, HN isn't a forum with a well-defined "expert" scope. It's a link aggregator for nerdy news. If you get bored with Rust, you talk about ChatGPT. Or CPU design. Or biotech. Almost anything goes.

I think this makes it immune to the patterns described in the article, although there are other ways for such communities to die. The decline of Slashdot is a cautionary tale.
