The RationalWiki IRC channel on Freenode is an odd little pocket community of RationalWiki. And by "pocket" we mean "nearly completely disjoint from the wiki". Of the regulars, most have accounts, and these are all inactive. Our Phantom Hoover (enterprising reporter) has surmised from the locals that Human and Cracker were present some time ago, but the only active RationalWikians to have visited recently are him and Electrified mocha chinchilla.
It is therefore clear that they are in fact the true leaders of RationalWiki.
As of 2017, it's dead.
