I've seen several people on Less Wrong recommend Mencius Moldbug's writings, and I've been curious about how he became so popular here. He's certainly an interesting thinker, but he's rather obscure and doesn't have any obvious connection to Less Wrong, so I'm wondering where this overlap in readership came from.
[EDIT by E.Y.: The answer is that he's not popular here. The 2012 LW annual survey showed 2.5% (30 of 1195 responses) identified as 'reactionary' or 'Moldbuggian'. To the extent this is greater than population average, it seems sufficiently explained by Moldbug having commented on the early Overcoming Bias econblog before LW forked from it, bringing with some of his own pre-existing audience. I cannot remember running across anyone talking about Moldbug on LW, at all, besides this post, in the last year or so. Since this page has now risen to the first page of Google results for Mencius Moldbug due to LW's high pagerank, and on at least one occasion sloppy / agenda-promoting journalists such as Klint Finley have found it convenient to pretend to an alternate reality (where Moldbug is popular on LW and Hacker News due to speaking out for angry entitled Silicon Valley elites, or something), a correction in the post seems deserved. See also the Anti-Reactionary FAQ by Scott Alexander (aka Yvain, LW's second-highest-karma user). --EY]
Speaking as someone who really dislikes Moldbug's viewpoints, it requires a very non-standard notion "fascist" to describe him that way. He has his own ideas for a model government which doesn't look much like historical fascism or even any other sort of dictatorship. "right-wing" is probably somewhat more accurate.
Moreover, it may help if you haven't to read politics is the mind-killer. Disagreement about politics with people (in this case a vocal minority of people here) doesn't make what they have to say automatically bad or wrong. And if anything, it can be useful rationality practice to listen to political ideas one disagrees with or even find morally repugnant. Having ideas that challenge one's status quo beliefs is a useful thing (in fact from reading this thread it sounds like some of the supporters of Moldbug here don't agree with him at all but think he has interesting things to say).
