I have most of the Fediverse-based account and seem to have just gravitated towards Lemmy over Kbin as found it very confusing, What makes you prefer Kbin over Lemmy or any other Fediverse instances?
Preferred the stock UI of Kbin, then I found out about userstyles and am in love with them. I'm a big fan of the microblogging, as it's a place for posts that don't warrant a full thread, but can still spark discussion. The politics of the Lemmy devs disgust me, so I'd rather not use a site using their software. Public upvotes/downvotes are great IMO, lets things be more transparent (like for instance I upvote all my posts, without it being public no one would know), plus it helps catch fake votes.
I also just find the name Kbin to be more catchy than Lemmy. Like GabeN, or k than.
