I just did this. Yes, leaving kbin.social was a bit of a pain since I had to resub to my communities manually, but it is a one-time cost. I think it has been worth it because I’ve been able to be way more active just because the Lemmy instance to which I moved is actually usable. The learning curve is not steep at all and the optional photon and alexandrite front ends are terrific. I’d encourage anyone to make the move.
