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?
I do have accounts on other instances, but thats really just for if my main one is offline for some reason. I use this one to sub and participate, no matter which instance the community is hosted on. ie the one we’re on right now is homed to lemmy.ml
