Yes there maybe some common sense approaches to curating things but Reddit has gone too far IMHO.
I think HN is a separate use case than is reddit. Which is why HN will never become Reddit nor does it want to. It's always been a niche site. Even though it's gained quite a bit of notoriety in the last decade. Most people outside of tech circles have no idea what HN is.
It's less of a separate case from a single subreddit in many ways. (although of course a subreddit can't influence a lot of the things that are differently designed on HN, so it's not like you could turn it into one and it'd just work)
You do realize how far from "moderators only remove illegal posts" HN is, and how much that shapes what HN is?
