I think people should pay (way) more attention to the domain name when creating a Lemmy instance. This is, of course, for admins of instances.
Instances such as lemmy.dbzer0.com and lemm.ee and such are just so unfriendly, in the name, that I think they do a disservice to Lemmy. They end up splitting the community. Due to the weird domain names, there will be privacy.lemmy.dbzer0.com, but the domain is just so unfriendly that people will also create privacy.lemmy.world and privacy.lemmy.ml and etc and it just creates unnecessary friction.
If you are considering creating a lemmy instance, please, please, think of the domain name. You cannot change it later!
So you basically saying people will tend to duplicate communities on lemmy.world just for the sake of friendlier domain name? Why do you think people use that logic when creating communities? Also, when you’re registered on some instance and you want to find communities you go to global search and use that, all from UI, and at that point you’re not even looking at browser address string, so why is that even important? You click to subscribe to communities, and then see them in your stream and your sidebar, domain name being completely irrelevant to any actions you do.
