I'm learning about the Fediverse and am confused about how federation is supposed to work. I understand that there can be communities with the same name in different instances, with different content. But I also understand you can subscribe to another instance's community. For example, there are sysadmin commnunities at lemmy.world, lemmy.one, and beehaw.org (among others). If we focus on one specific community, let's say [email protected], we can find that community from any of the instances. If I go to each instance and look at [email protected] from each one, I can see the same pinned post is at the top of each one instance's view ("Calling all /r/sysadmin reddit refugees!" by DarraignTheSane).

Great!

However, if I look at that pinned thread from each of the three instances, the comment stream is different. The post itself is the same, but the comment thread is a mixed bag. Some comments seem to appear in multiple instances while others only in one or two, but never all three

lemmy.world shows 11 comments lemmy.one shows 6 comments beehaw.org shows 4 comments

On lemmy.world, the second newest comment says "Nice! It feels like home." This comment also shows up on lemmy.one however not on beehaw

The newest comment on lemmy.world says "yeeey" but doesn't appear in any other instance's view of [email protected]

This is just one specific example. Are you not supposed to get the same content, when looking at the same community, regardless of what instance you are logged into when viewing it? Or am I missing something?

That's the idea, but the reality is turning out to be very different with defederation. The result is two users looking at the same post see different content, which is not a great look for an aspiring reddit replacement, frankly.

I think the multiple communities of the same topic across different instances is a mistake honestly. Information/discussion should be concentrated, not spread about a bunch of places.

I read on here they are working on a method that would allow communities across instances to merge. I hope that happens.

Imo, federation should mean the same communities are replicated across all instances. If an instance wants to house its own content, they can maybe make a community that isn’t replicated to all the others but accessible nonetheless by everyone (ie Piracy community, maybe not every instance owner wants to replicate that to their instance).

I dunno, the bifurcation of communities just seems like a mistake and less efficient than everyone in the same place sharing knowledge and ideas.

I dunno about this. I REALLY like the idea of fragmenting the whole user base. When a community gets too big it ceases to be a community.

Why does the whole internet need to see then same content, and be a collective hivemind?

Whats wrong with the current user size we have on this current community? Id even argue its too big already. If it blows up by 100x we run back to having posts with 10k replies, 20 or so which everyone will read. Its a really dumb system

I like both, in their own time and place. For memes, news, etc? I don't usually need to comment on those posts, but I do like there to be a steady stream of new content from a bunch of people. In that case, I'd love there to just be a bigger community, even if I don't feel like my comments (if I made them) would be read.

However, if I'm trying to have discussions about Magic, Zelda, teaching, or cooking, then I would rather have the smaller community to actually have discussions. Even it that case though, having one place as a "news aggregator" for that hobby would be nice.
