That's what I was thinking about.
I have to acknowledge the point @otter@lemmy.ca makes about there being a collision with the term "community" in the threadiverse perspective. Maybe "home" or even "tribe" or "people" would be a better fit. But I still do think that "community" encompasses the feeling best, and that collision will be promptly resolved once the user understands what communities really are on that narrower scope.
That's maybe a compromise we will (have to | want to) make.
Once again - that's my feeling, but I could be wrong.

And the term would reinforce the need do stick to that entity rules. I agree.
