Kbin is federated with Lemmy and other fediverse services, however to stop the Rexxit hug of death, the kbin.social instance of Kbin were forced to temporarily turn on Cloudfare protection which breaks federation. They’re working on it though.
I’m commenting to you through fedia.io currently. It’s a Kbin instance that is federating properly (probably because of the lower traffic levels as compared to kbin.social).
SU stumbled (I can’t remember why)
They attempted to make a social network out of it, and I think a link aggregation site like Fark.com or Reddit are more engaging because you don’t generally leave the site - or at least not for long. With SU you were constantly on a new site.
It’s not terribly dissimilar to what Reddit is doing now: trying to force through a change that nobody wants, nobody asked for and one that’s making the experience worse.
I do often miss SU, but sometimes really great information hides in the comments section on Reddit. SU’s shoehorned comments section just wasn’t the same thing.
I’ve bought far, far more PC games since I got my Steam Deck than I ever had before. This thing rocks
