https://lemmy.ml/c/nba@lemmy.world Or !nba@lemmy.world is the community I’m talking about.

Seems to have gathered more people. Don’t know why, but in these quickly changing times chance is probably a big factor.

No reason multiple communities can’t survive, but realistically, as we know from Reddit, one will often dominate.

Sorry for the mod here if they were keen to start a community. From what I understand, moderators of a community need not be all on the same instance, so maybe you could help out over on lemmy.world. It seems they might want it too.

Lemmy.world should be a stable instance as it’s run by @ruud@mastodon.world who runs a number of instances including a fairly large mastodon one.
