I really appreciate his books, <i>The Black Swan</i> and <i>Antifragile</i> particularly, though it does seem to me he's set up something of a cottage industry churning the same general idea into a sequence of very similar books. Then again, as long as he has extra stuff to add, and a readership willing to purchase them, I suppose this is utterly acceptable.<p>However, as a person, he seems to be an absolute rabid nutter. At one point he was planning to publish a book of his own aphorisms, as quoted by himself, while he is still alive. He rants and raves on Twitter[1]. Lately he's been engaged in an utterly hysterical tirade against a historian about the ethnic diversity (or lack thereof) in Roman Britain... whichever side you take in this at an intellectual level (personally, I'm more on his side than not), the tone and mode of the conversation as conducted by him is absolutely rabid and unacceptable.<p>[1] Full disclosure: he banned me on Twitter years ago because I fucked up an integral he had posed as a question for followers. Make of this what you will.
