Was super invested in it (was considering moderating multiple magazines), as I really like Kbin and the vision of it being an all-in-one microblogging and link aggregator platform in the Fediverse. With there being so many federated platforms serving the same purpose, I like how Kbin sort of went against the fragmentation. Had to leave it for Lemmy just the other day as well. I think that Ernest has created the best alternative to Reddit despite the struggles he's faced with development and maintaining the instance alongside with personal issues.

mbin looks great but I think I'll just stay with the more stable option and community...being an early adopter was fun for a year though. I'm still a little iffy about mbin personally. If there's a mbin/kbin API release I may reconsider.
