It seems to me that there are several factors. Firstly, the instance was created recently, about 1-2 months ago. There wasn't even an official instance opening, you know, with cake and confetti ;) During this time, I've been observing people on the Fediverse. It's unlikely that any follows were given by chance. Later on, wonderful people who discovered kbin did the rest. That's how it is in the Fediverse. In the beginning, not everything is easy and obvious, but if you put enough heart and effort into it, it pays off in the future.
