Yeah, unfortunately i dont have any answers there. Obviously i have no ways to influence other instances, but it will be interesting to see what happens in the future as lemmy continues to expand and grow. I would suspect it will probably play out like reddit, where there are duplicate communities (albeit with different names on reddit) where one gets far more popular than the other (say r/dnd vs r/dungeonsanddragons) and people naturally gravitate towards the one they prefer, the larger community or the smaller one.
