Thank you! At least I don´t feel so alone now. :)

we’re way past the point where reorganization into a structure like that is feasible

I am still optimistic about it. It will be impossible to make one huge push in this direction, but slowly people will come to realize that this is the most sensible approach. For example, I’ve noticed that !nba@nba.space started to get more activity because !nba@lemmy.world is considering moving out of LW, but are spending a lot of time debating over a lateral move. If only they had accepted when I first invited them to join as mods from the topic-specific instance, this would’ve never been an issue.

Look into tags.pub. You can follow hashtags and lets you find things according to the topics that interest them.
