Martijn I sometimes see quitter.no come up as a place where people have their GNU social pages. Kevin Marks (kevinmarks.com) from #IndieWeb has a page there (quitter.no/kevinmarks), but I think he too is only cross-posting there instead of using it primarily. I don't think it ever caught on outside of the anarchist and activist communities, who want their anonymity guaranteed and no censoring by the companies who own the other social networks.
