Only the moderators of the big subreddits. The users that aren't bots are largely reasonably normal people.

Yeah, there's sort of a bell curve to the ideal reddits where everything in the middle is totally serviceable. However, too small and the mods become overwhelmed and have to overban/overmod to keep up. Too large and the mods get powerhungry and ban in accordance with their own political values.

Yes, although I think the latter is carefully organised, probably by well-funded groups.

E.g. /r/worldnews have 36 million subscribers, and I think it has more influence than even big newspapers, and this is controlled by anonymous moderators, who for all we know can be a team working for the same organisation.

X for me takes the crown these days.

Dominated by crypto grifters, Musk sycophants and engagement farmers.

At least Reddit isolated those to certain subreddits.

Reddit is highly censored and can get you banned easily unlike X.

Hey, Stack Overflow is pretty high up there now
