I've been (rightly) downvoted for pointing this out on HN in the past, but one of the main developers associated with the Urbit/Hoon/Tlön/Uqbar/etc project is someone active in the alt-right (although there may be something to say about whether or not that has anything to do technically; I wouldn't know or particularly care).
It doesn't make sense to call him active in the alt-right since his blog finished in 2011 and the alt-right didn't exist back then. You probably mean neo-reaction which is highbrow right-wing idiocy and not populism.
