I will preface this by saying I think it would be interesting to attempt but I think the end result would be disagreements of all kinds would lead to a lot of degeneration and splitting as we see with Lemmy and with how gab and parlor are in relation to mastodon and such.

There already are “forks” of wikipedia for conspiracy nuts and other sorts.

I think what could work though is similar to how some things are adding AP support that allows for following and sharing, and maybe commenting on articles, having those aspects be federated might not be so bad.
