I like that Lemmy can post on other instances (communities on other instances), but thinking about it, would that not present a potential issue with centralizing information about a topic on one instance?
I know it's kind of similar to having themed Mastodon instances (and I also don't really understand those), but it seems like a potential issue?
I know multiple instances can have the same communities, but that then seems like fracturing the conversation?
Could this just be due to my limited knowledge/use of the fediverse?
It's not like reddit is any better about fracturing. There's two different San Diego subreddits because the mods hate each other. There are plenty of other examples but they are rarely talked about.
That’s a good point! Most of the subreddits I use aren’t too fractured, but that being the case for larger ones, it’s not too different from Lemmy.
