Consolidation is a big requested feature. Well, we can do that today with bots. Instead of Reddit-reposting bots, lets use Lemmy-bots to repost and consolidate Lemmy communities together.
EDIT: The community will need to be moderator only, the bot should be a moderator. Posts/comments should be mapped to the original topic. I think the only feature needed from Lemmy-developers is some way to globally link to a topic? But we can kind of work around that issue by making a consolidation-bot / consolidation-community be server-specific?
Hmmm, might as well experiment and see which works out better. I’m not quite convinced that your way is better yet, but I do see some advantages.
In any case, the problem to be solved is consolidation. Seems like multiple solutions are possible.
