I'm glad your favorite community has sustained itself for 20 years, but with this statement you remove it so far from the category HN belongs to that it's incommensurable.
It's great that there's room for lots of different internet communities to thrive with different strategies. I've always felt there's room for many more—there are lots of opportunities for communities to start with different initial conditions and grow into qualitatively different things. I wish people would start them. But let's not pretend that they all have the same problems. HN's category is that of the large, public, anonymous internet forum, and all its hard problems stem from that category.
