Seeing stuff about reddit being posted to 10 different technology boards, plus reddit-themed ones, then reposted further just makes this whole idea a mess. Reposts have to be consolidated into a single comment thread.
There was just an update posted regarding lemmy that would allow for community merging. This is really going to be a game changer if they can figure out how to work that properly.
This sounds like a feature that couldn’t be implemented properly without users being confused. There are different posting rules for each community. It would be too much to keep up with.
Consolidating communities could be done sort of like multireddits, basically just an organizational tool, which didn’t confuse people about the different rules, because it was clear which subreddit individual posts were on, and rules were clearly displayed in sidebars.
It could work in a different way, where the communities are more thoroughly merged, but there would be no reason for it to be anything but voluntary for the moderators of the individual communities. Presumably, the rules of the combined community would be something that would be discussed and decided on between the moderators of the individual communities that would enforce the rules.
