Yeah, I don’t think asking communities that are already fairly small on Reddit to create the same community on Lemmy was a good idea.

For something like this it’d be best to start with a single community for the whole broad topic (like, ImaginaryStuff). Hell, Reddit used to be a “single subreddit” originally. And the niche subreddits didn’t pop up until fairly recently where they were actually able to entice enough people to use them.
