I think this sounds like a good idea. A problem when starting a community is that one wants to find a stable home; it might make sense to set up camp at, say, hardware.watch, but without knowing who operates it it might feel more uncertain than lemmy.world.

And then, as a result, if lemmy.world ever disappears or has problems, it'll take way too many communities with it.

If these topic-specific instances had some sort of collective ownership, I guess we could more effectively guarantee for their continued survival, and it might be more tempting for existing communities to move over there.

I'd be interested in hearing the thoughts of some admins - would [email protected] be interested in moving to [[email protected]](/c/[email protected]), given the right organization?

And a piece of constructive feedback: Vague community names like [email protected] is probably less likely to attract attention than something specific like [email protected] - when searching for a community, people look up the community name rather than the domain.
