It might not be much of a loss. The average quality of answers there has been below mediocre for as long as I can remember.

Lots of people eager to earn points by showing off what they think they know, relatively few who truly understand the nontrivial issues, and the former often drowning out the latter. The result is like Reddit for programmers.

The moderation system also seems to optimize for mediocrity, often closing questions as opinion-based if there’s even a hint of nuance.

I used to spend time there every week answering questions on subjects that I understand well, but competing with broken incentives in an ocean of know-it-all personalities was tiring, so I almost never bother any more.

I would like to see something replace it. I don’t know what form that should take. A collective knowledge base with a culture like that on Hacker News would be interesting, though I don’t know if that’s feasible without someone selecting and paying good moderators.
