I was inspired by https://bossportsnation.com/2024/02/07/where-are-mls-fans-gathering-online/ so I did some analysis of where MLS fans are hanging out in the fediverse. You can find the data here: https://docs.google.com/spreadsheets/d/1bh70eldw1Xf04sUjVFx0KIhWy97UF_HZTYwSSspEwD0/
In olden times, I had a multi reddit with all my soccer subs in it so I could see them all in one place when I wanted to, but wouldn’t accidentally see them while doom-scrolling through All. I don’t think that capability exists here.
I also don’t think Lemmy has that feature, though many clients make it easy to manage multiple accounts, which you could use to approximate that behavior. Mastodon has lists, though, which totally do that, just in case you’re into that format as well. I definitely agree that I want “multi-communities” — I’ll see if I can scare up a GitHub issue to comment on with our use case to see if that encourages the dev team to pick up the feature.
