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?
That would require such a massive change in the way the platform works, and it would be way more difficult to moderate.
A multireddit equivilent would probably make more sense.
