I'm personally longing for transparent moderation logs (like lobste.rs does) coupled with user-elected moderators. AFAIK this was one of the defining features of Aether (https://getaether.net/docs/faq/voting_and_elections/) but it's still in development.
I hadn't considered the transparent moderation logs before but that's a great idea, so props to lobste.rs for that. Not sure that I've seen Aether before either, I'll have to check it out sometime.
