The lemmy ui could add a way to group communities at the user level. Something like multi reddits.

I also struggle to see the issue here. People will subscribe to the various communities across instances, and they’ll quit the ones they don’t like, thereby making the best ones rise to the top, just like it works across subreddits of the same topic.

I guess the concern is discoverability? On mobile web, Beehaw’s homepage show “Local” (not sure if just Beehaw or all instance). It’s true that it’d be good if the default was “All”, so discoverability isn’t fragmented.

I don't think this is a problem. It's the same on reddit where you can have multiple gaming subreddits or multiple news subreddits. Eventually the communities will consolidate.

Here is an issue that would solve this, but ideas are welcome.

We just need a more user-friendly way for all the !gaming instances to be grouped together, with users having the control of adding/removing what makes up their personal !gaming on their chosen fediverse instance.

I think a good solution would be to split popular communities across instances to balance the load on the servers. Also you could have stubs that say the community is actually located at xyz etc.
