I think your suggestion is a bit out of scope for what's actually being discussed/not really a solution.

I'm active on the somewhat (not fully) decentralized social medium Fediverse (more widely known as Mastodon, but it's more than that) and I think a lack of curation is a problem: Posts by people who post a lot while I'm active are very likely to be seen, those by infrequent posters active while I'm not very likely to go unnoticed.

How would your proposed system (that seems a bit utopic and vague from that comment, to be honest) deal with that?
