The content on all the communities seem different.
Why didn’t the “copycats” get the “this community name has already been taken” message?
It was bad enough at The Other Place finding one overlooked sub about one of your interests.
Now you have to find every single community in every single instance if you hope to talk about your topic?
I mean, look at this:
No Stupid Questions@lemmy.world
No Stupid Questions@kbin.social
No Stupid Questions@lemmy.ca
No Stupid Questions@mander.xyz
For now yes, but over time probably no. Multiple communities around the same subject are created on different instances. They’ll compete to become the most active one. Then everyone will subscribe to that one, and it will grow even more. However, if over time you don’t like that one any more (e.g. don’t agree with the mods) you can start a community with the same name somewhere else and compete again to become the most active one (or not, and stay small if that is preferred).
