This is remarkable. Looks like #KBin instances already have more active monthly users than #Lemmy instances.
It's notable because Lemmy had been around for a while, while KBin is a relative newcomer to "federated threaded news discussion" space on fedi.
It's also great, since Lemmy has certain problematic tankie legacy (although there are plenty of instances that are absolutely not supportive of that stuff).
