I've given up the idea of finding people I already know on other social networks. More or less everybody I know personally is on Facebook, and perhaps Instagram. I guess there's very little overlap in interest between me and my peers, or maybe I am just interested in doing stuff online that isn't just posting pictures or watching videos. I'm glad Sublevel exists, it is very much different than other social networking options out there, and in a good way.
