We should implement this as whenever I wish to browse (for example) technology@lemmy.world I have to go to there, and whenever I wish to browse technology@kbin.social I have to go there. Would it be possible to implement it in kbin/lemmy’s code to make it easier to browse all?
I just don’t think this is a problem which needs to be solved. On Reddit it’s common to have different subreddits focussed on the same topic. For example, r/Games and r/Gaming. The only difference on Lemmy is that they’re now m/Games@lemmy.world and m/Games@kbin.social. Yeah, it’s slightly longer, but super easy to solve using UX tweaks in the front end.
What’s more, this proliferation of communities across instances is critical for a reasonable user experience because of the apparent widespread support for defederating from instances which aren’t ideologically aligned. If people get comfortable with using one uber gaming community on one instance, that instance could disappear from one day to the next because of a capricious instance owner.
