I’m not sure why you’d knock one platform for it but not the other.

Time and scale of use of Lemmy is much greater, therefor more problems have been identified and fixed. It’s possible that kbin devs are smarter of better or have been able to benefit from observing the experiences of Lemmy devs, but non of those are safe assumptions without specific knowledge.

It’s also possible that the kbin design is simply a better one for any number of reasons. But we won’t know that until is gets much more use by many more people. Lemmy has that “advantage” now, thus the safer bet is on Lemmy.

It seems like the Lemmy devs are not interested in creating the feature of following individuals. Unless someone forks the project to add it, anyone who wants that feature should give kbin a try. I’m not one of them.
