This is going to require further investigation. I knew very little of this social network other than it was for various interests and that I saw it shilled on YT sometimes. The thing that strikes me is that it seems pretty active. How much OC is here? How does this interact with the other fandom ecosystem? I mean, if even half those memebers were active that could be a significant force upon the fandom. Yet, I can tell you that I do not see near as many people quite this tier in other places. So it is isolated?
