I’m sure this question has been asked and answered many times, but I can’t seem to find the info.
My naive understanding is that a given community lives on a certain server. For example, this post is at lemmy.ml: https://kbin.social/m/asklemmy@lemmy.ml/t/107757/Is-anybody-else-more-active-here-then-they-were-on
Then, I figured that when I visit that post from kbin.social, I figured it would pull the comments from the lemmy.ml community and that no matter where you view a post, the comments would (eventually) be identical. However, the comments are very different at https://lemmy.world/post/746839 which makes me think that I have a pretty fundamental misunderstanding with how things work.
Nah, you’re good. For unknown reasons federation between kbin and lemmy.ml in particular is just fundamentally broken right now. There is some talk about this on lemmy.ml , there are a couple of threads about this topic on kbin as well somewhere, the most popular here.
Essence: Lots of speculation, nobody knows for sure, participation on lemmy.ml hosted discussions from kbin seems to be impossible right now (I tried, to no avail), federation between kbin and other lemmy instances does not seem to be impacted to the same extent, if at all?
