When I look at https://lemmy.ml/c/startrek vs https://kbin.social/m/startrek I see two entirely different lists of posts. Why? It’s the same topic, just on different instances. How can we have communities about topics without having them siloed into their own instance-based communities? Is this just related to that 0.18 issue with Lemmy/kbin not talking nicely, or is this how the Fediverse is?
Is it (at least theoretically) possible for me to post an article on https://kbin.social/m/startrek and have it automatically show up on https://lemmy.ml/c/startrek, or are they always going to be two separate communities?
I would dispute that, actually. Sometimes people make separate communities because they want there to be separate communities. Over on Reddit that required you to make communities with different names, but here you can also do it by going to different instances. Maybe there’s a [email protected] that’s all about how awesome the Romulans are, and [email protected] wants nothing to do with them.
If that’s the case then your “problem” will be self-correcting, if there are multiple threads on the same subject in different communities people will tend to contribute to the larger one and it’ll snowball at the expense of the others.
Some people might prefer the smaller communities and threads, though, and thanks to federation they can pick whichever one they want.
