I am new and trying to understand how Lemmy works. I am posting this from my lemmy.world account, on a lemmy.ml community. It seems like you can read, post, subscribe to whatever community outside of the instance you’re registered with. So… Why register on lemmy.world vs lemmy.ml or any other instance, if all communities are accessible to everyone?
it basically comes down to personal preference tbh, each instance have slightly different rule sets and internal communities, lemmy.ml / lemmy.world are simply some of the ‘main’ instances, They’re higher on the list on the instance search and thus generally gather a larger crowd because people see the higher user count and just go with that.
and if you don’t like any of the public instances you can simply role your own and use it as an internal friends chat that can also browse the external fediverse
