last year, there’s been a suggestion to turn RSS feeds into their own federated-social-media of sorts via OPML blogrolls:

here’s a deeper deep-dive into the topic:
the addition of blogroll support will go hand in hand with writefreely’s vision of an open blogging sphere, will expand upon its current ActivityPub federation capabilities, and will be good for discovery among users.
not to mention that a few competitors already implemented this or something similar:
