Interesting idea. Personally, I would like to see larger groups of admins and server members working together towards common goals and setting common standards - what we have right now is more like a confederacy, not a federation. There is no unifying, governing body made up of representatives from the servers.

Let's go simpler: what if your instance was allowed to copy the fed/defed lists from other instances, and use them (alongside simple Boolean logic plus if/then statements) to automatically decide who you're going to federate/defederate with? That would enable caracoles and fedifams for admins who so desire, but also enable other organically grown relations.

For example. Let's say that you just joined the federation. And there are three instances that you somewhat trust:

• Alice - it defederates only really problematic instances.
• Bob and Charlie - both are a bit prone to defederate other instances on a whim, but when both defed the same instance it's usually problematic.

Then you could set up your defederation rules like this:

• if Alice defed it, then defed it too.
• else, if (Bob defed it) and (Charlie defed it), then defed it too.
• else, federate with it.

Of course, that would require distinguishing between manual and automatic fed/defed. You'd be able to use the manual fed/defed from other instances to create your automatic rules, to avoid deadlocks like "Alice is blocking it because Bob is blocking it, and Bob is blocking it because Alice is doing it".

We can't even merge similar/identical communities across federated servers and now we have this idea?

Can someone ELI5?

Reddit's multireddits (a combined feed from multiple reddits) are a small step in this direction on a centralized social network, and there have already been requests for similar Lemmy functionality ("supercommunities")

They are already introduced into /kbin - as Collections

Part of the problem here I think relates to scale.

If I invite a load of friends over to my house for a party, they might be in different rooms having different conversations but they’re all my friends in my house. No one cares who I let in or kick out, certainly not either of the next groups.

Let’s say I’m part of the committee for the local community hall. We let our halls out to clubs. Some of the committee go to some of the clubs. I might not be interested in what it is, but if someone I trust says they are OK, I’m OK.

At the local University they have a lot of spaces, each managed by the respective school. Each school has a slightly different ethos. Some of them might let their space to groups that other schools wouldn’t, but it’s not their call. They share some resources but not decision making.

We’ve got this problem emerging. The decisions made by lemmyworld or other large instances are generally in service to their communities, whereas on smaller or more focused instances the instance level decisions are the same as community level decisions.

It's an interesting idea, but too complicated to be put into practice IMO.

I'm a fan of the idea. Are their any implementations are in the works or running now?
