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]
I don't even think they're particularly vocal. I can recall like two loud Moldbuggians: Konk and Vlad_M, who is inactive and doesn't even mention Moldbug by name, to my knowledge.
I think it looks like these Moldbuggians are active because a lot of Moldbuggianism is deconstructing assumptions about how politics works. So there's a lot of mainstream ideological assumptions that aren't seen as ideological at all by most people (democracy is good, the media is an observer not a participant in government, etc) yet are seen as incorrect and/or political claims by Moldbuggians. So then Moldbuggians say things like "wait now, democracy isn't all that great" and it looks like they suddenly injected Moldbuggery in a non-politics thread, when they see it as just adding another comment on an existing politics thread.
I haven't read Moldbug, so maybe you mean something else by this than what it sounds like, but I don't think I know of anyone with an interest in politics who'd agree with this statement as written. Pretty much everybody thinks that the media has a huge influence on government, up to the point of often determining what decisions the government can make, and which politicians grow popular or fall out of favor. There's a reason why it's called the fourth estate.
