If I understand Lemmy correctly, you can create duplicate communities on different instances. Isn’t this kinda counter productive because this may lead to less user interaction in those communities, because the user base gets split up between competing communities.
Is there a way to fight this division of the (small) userbase or is this effect even desired because it leads to more tight knit communities on the different instances?
There were duplicate communities all over Reddit too, as long as he didn’t have exactly the same name there were lots and lots of subs that had more or less the same content with overlaps of subscribers. Whenever those duplicates eventually one will pull ahead and most people will be active there.
