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?
For some cases, like photography, pets and landscapes communities, where I probably will not comment, I decided to follow them on Mastodon instead of Lemmy. This way I can keep my Lemmy timeline cleaner.
