I’m very new here but I decided to check and compare the posts in a community on lemmy.world (where I have my account) and that same community on the instance where it resides and the posts were almost all completely different! Is that how it’s supposed to work or are they supposed to be synced? Sorry if this is a noob question, I’m new here
that’s what I did. I subbed to (for example) memes@lemmy.ml and viewed c/memes directly on lemmy.ml and it had different content
Right now its a bit of a mess while things are quickly developing. Ultimately, federated communities should look the same across the fediverse, with a slight delay.
There are some caveats to that around defederation.
