This post assumes you have a basic understanding of what Lemmy and Kbin are. Which, in turn, assumes you understand at least the concept of federation.
The Issue Currently, the way Lemmy/Kbin (which I will refer to simply as “Lemmy” for the rest of this article) work like this:
Cool, so our user can access content from both instances. They go to Instance #1 to talk about transporation, and Instance #2 to talk about animals.
Tags is a cool idea to help users find posts or communities on specific topics.
But taking away the different communities on the same topic is misunderstanding one of the key benefits of the fediverse over Reddit. I might want to talk about horses in a different way, with different people, operating under different rules, to the way others might want to talk about horses. The fediverse allows that, without having RealHorseTalk and RealRealHorseTalk nonsense.
Better UI and categorisation tools, yes. That’ll help make sense of this for new users. But don’t take away an actually positive aspect of the fediverse just to make it look more like Reddit.
