Kbin.social was my first too, Ernest was a king and I hope he's doing well and thriving in life.

Made a handful of alts when it became clear kbin was going away. Ended up using .zip as my main as I like their hands-off approach to moderating/defederation. We're federated with everyone except malicious/criminal instances by default. If you don't want to see things you need to block them yourself which I like a lot.
