There is some unexplored potential in opt-in moderation systems. Where instead of singular entity providing content distribution, content amplification and content moderation you can pick and choose what topics need to be filtered and what teams/individuals will do the filtering for you.
More like Reddit minus global rules. But I also see differences. Subreddit admins manage both feed and comments. Here you can have that decoupled. The fun bit is comment tree moderation. Imagine different subtrees culled for different people - effectively no global view on a comment section (unless you disable your user/comment moderation sources temporarily).
