I just browse All the subscribe to communities I see and like. One thing you’ll find on Lemmy is that a lot of the communities are just Lemmy equivalents of Reddit subs, so if there’s one you like you can just search the name of what you like. It’s usually a case of find the version of the sub you want that’s the most popular. Because this is Lemmy and there’ll be different instances of the big subs, like if you want funny you might find funny@piefed.social or funny@lemmy.world, and more. There’s usually one instance which is the one to use. I understand they’re in the process of fixing this by having it so that they all sort of subscribe to each other and you can just follow one to follow them all. Unfortunately doing this involves using the search which I also find pretty terrible but I understand it’s also a priority issue they’re fixing right now.

The upside is that I don’t scroll down my feed and see the same post 20 times.

I get what you’re saying but surely a lot of these problems are already present. You can ban a user but they can just go create a new account on a different instance and go back to posting wherever they want.

Personally I’d like to see some kind of tracking thing so Lemmy’s aware of duplicate posts and then the client can be configured how to behave according to user preference.
