Searching lemmyverse.net yields the following:
None of the communities are actively moderated, and only .world has activity in the past month.
Is this a case where consolidation towards .world is permissible, or would it be wiser to consolidate towards one of the smaller instances?
Personally, I say we go to another instance. We need to diversify the communities on Lemmy, and having everything on .world will lead to problems.
