Lemmy has everything that Reddit does. It's federated - I would recommend lemmy.world or lemmy.ml for people from HackerNews

Honestly I’m not so concerned with either.

Reddit: Except for the larger subreddits, on the smaller ones moderation is done by a few people where common sense still seems to rein and fake news is quickly called out. As long as Reddit doesn’t start censoring topics which the Trump government now considers controversial I don’t worry.

Hacker News: I do not worry about that either. Though since the election results a few unconditional Trump supports seem to come out of the woodwork, common sense still seems to be the primary tone here.

Those are really my personal criteria: Sane moderation, no hiding of topics that might be controversial to the new government. In both of those Twitter, and from now on Meta seems to lack.
