Specifically, I’m trying to post (an image) to boston@lemmy.ml from my account on kbin.social. The post shows up on kbin.social, but when I go to https://lemmy.ml/c/boston, it doesn’t seem to be there. Is there something special I need to do to ensure it’s viewable?
Kbin.social is now the largest single Reddit clone on the Fediverse IIRC.
Lemmy is still bigger if you combine all the instances, but Kbin is the largest single instance. Kbin hasn’t really seen other instances be created yet though (anecdotally, I hit some snags trying to get my own instance set up).
I also hit some snags. Did the docker image not compile for you, either?
