This got five upvotes within a half hour or so, surely enough to have hit the front page. I can only assume that it's being held back by people flagging it, a reaction likely based on not much more than a knee-jerk reaction to the name "Mencius Moldbug" in the title. If they would only read the article, they would see that it's not only totally on-point, but also that there's deep irony in flagging it. It's the Hacker News equivalent of the heckler's veto—the very phenomenon decried in the article.
