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?
Why fight it? If they want 3 different asklemmy instances, let them. Eventually users will flock to the most active one, or there will be parallel ones. Then it’s on you to either join all or stick to whichever one you feel most welcome at.
