I don't really; I'm just hedging my bets. I have noticed that kbin doesn't seem to go "down" as often as my Lemmy instance; on the other hand, there are still some bugs going on with kbin and I don't like that you can't yet collapse comments in threads. (unless I've missed something.)
I think Kbin has a lot of potential. I also think changing the name to something more catchy would help it grow more although IDK.
Userstyles?
I mean, share?
