"Gnuinos, Refracta, Exe GNU/Linux, Nelum-dev1, Star, heads, good-life-linux and Crowz."
The sheer # of obscure distros. I'm wondering how many have essentially 0 regular users outside of the developer(s) themselves. They use the distro to develop the user-less distro. At best many probably have users who install, test, wipe and move on to the next in the distrowatch list, for fun.
