Like you have a small community of a few active people, but there’s federation with a massive community with lots of users - which posts are “better”?
I think this is where federation will get the most interesting. It would be cool to add/remove weight to some instances and communities. And each instance's software could handle this differently with different algorithms.
I'm completely speculating because I'm high. I have no idea what Lemmy's roadmap looks like. Would be cool though man.
