For example, I’m on Lemmy.ml and I’ve joined !photography@lemmy.ml, !photography@lemmy.world, and !photography@kbin.social. In this example, it’s not very different from the number of similar groups on Flickr but, in comparison to Reddit, it seems like the decentralized platform can be a little unruly.
How are you going about joining different communities and managing your engagement? Are you only participating on the community on your instance? Are you joining and posting in as many instances that seem relevant?
I was a heavy user of multi-reddits, which is a direct analogy to what you’re proposing. It was common to see crossposts and I never felt it needed fixing. As different subs had subtly different cultures, you got multiple perspectives that way.
