Not entirely, but neither is it extraordinarily healthy either. We'll see what develops - e.g. maybe its creator will emerge from a binge of programming and it'll become better than ever.
I still doubt that I'd go back after leaving it though - I waited so very long for it to improve, but it only ever seemed to get worse (performance wise), and it has major structual issues too, e.g. all final-say decisions controlled by a single owner who does not communicate much with the outside world.
In fairness, Kbin was not nearly as advanced as Lemmy when the Reddit protests and migration occurred, so a great deal of catching up was inevitably necessary.
