But how come some instances show posts from more communities than others? How come i can register the same username multiple times on different instances? How come it’s so difficult to subscribe to a community from a different instance?
The “showing more communities” part is called federating. basically, an instance (@lemmy.world in ur case) has a bunch of communities. now the owner of that instance can “federate” with another instance, so that you can additionally view their communities as well.
I’m a complete newb with Lemmy as well, but as far as I know, lemmy.world for example only defederated some extremist instances (and threads if I’m not mistaken?)
you can use the same name because, similar to an email address, the instance is part of your username (eg: asdf@gmail.com is different to asdf@hotmail.com) your app / site may just hide the end part
the subscribing problem might also just be on your app specifically, as i have no problems subscribing
