Yeah, it's expected to take pride in something like that only because it's been us vs them for almost as long as the internet has been around. Now we can all access everything everyone else can access (hi from kbin!), so there functionally IS no "them."
I've been trying a lot to shift my own mindset because not only is it just....making another reddit situation if we put all of our eggs in one basket, being competitive about someone else's instance is literally the same as being mad at someone because their phone uses a different area code. You might get a general idea about them if they have one that's well known, but culture is the only difference between any of us. And with federation, even that may not stand the test of time.
I don't know if it's temporary, but you can't post from Lemmy.world to Kbin, or even see any federated content from KBin. Also, anything I post from KBin doesn't show up on Lemmy.world.
Also, if you go to Lemmy.world and view this thread, there's 174 comments and counting. They aren't showing up here. Something is wrong with Lemmy.world federation.
Your specific communities might not have established the pipeline yet. But the federation between world and kbin is open. I can see posts and comments for my content on both sides, even at the time of your post.
I did think it was oddly slow for a headline like this, but I mostly likened it to posts getting any attention on the fediverse being like roulette still. Has to be temporary, I know it's been spotty for at least a few days. Is sad for the time being, though :(
I've been investigating this more. It seems to be a problem with Kbin.social... I can view anything on lemmy instances from Kbin, but I can't view anything on Kbin from lemmy instances. I can't search my own name, I can't search Kbin.social communities from Lemmy (tried lemmy.world and beehaw.org) ... so I don't know what to do. This problem basically kills kbin.social for me if it won't federate properly.
If its something small and niche, use the general kbin search bar and search for the full lemmy url. This will "establish" the connection and get things running with some time.
you can do this for communities/magazines as well. If you're the first to search, it won't show up, even with @instance looking.
It was tongue in cheek but seems like a weakness in the federation model unless I miss something.
I look forward to the Lemmy wars. I hope we get a good 5 years before the opportunists figure it out and start exploiting the 'power' that will come with who can federate with you.
