Kbin doesn’t seem like it’s going anywhere. The repos are dead (one commit in the last two months, written in php which is not promising for new contributors), there’s really only one instance of it, and I don’t know of any communities hosted there. There’s also no app support, which is crucial for me to actually use the platform. The concept is good so I’d love to see it continue, but I also wouldn’t invest anything in the platform at this time.
