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?
Another interesting thing I realised: In a centralised network like Reddit, if the site goes down, nothing is accessible. But if a Lemmy instance goes down, most, if not all communities you’re subbed to should still be up given they aren’t hosted in that instance.
It depends of where the communities you’re subbed to are hosted. Like currently a lot of communities are hosted on lemmy.ml. If it goes down a lot of communities will still be unavailable but you can still browse the rest.
