How is Lemmy dealing with multiple communities on the same topic? - Lemmy.world

I come from Reddit and been enjoying Lemmy so far. How is Lemmy dealing with multiple communities on the same topic? To me: - If the communities are all active, then I shall subscribe to all of them, but end up having lots of duplicate/similar posts on my feed - If there is one community that is dominating, then what is the point of federation? I was subscribed to [email protected], and just because I actively went into it, I saw a post that the community was frozen and they decided to use another android community on a different server, to avoid fragmentation.

I think this could be “solved” on client side. On Reddit you could (can? Idk) merge various subs to a single view, maybe clients like Memmy could do the same.
Merging multiple communities like in a Reddit multisub would not solve the issue of duplicated posts in one’s feed.
Nothing solved that problem on Reddit either =]
The way I use multis in Reddit is to create bigger topics, and I rarely see duplicated posts. For example, in Reddit I do not have a multi for subs /r/android1, /r/android2, /r/android3. However, I have a multi for mobile OSs, grouping /r/android and /r/iOS. Rarely do I see duplication.
