Zero: Elon Musk
For his attempts to make electric cars sexy and space tourism feasible, the PayPal billionaire and CEO of Tesla Motors is considered a hero by many. But when Musk responded to a negative review of his supercharger stations in the New York Times by calling the reviewer a liar -- complete with selectively chosen data points that demonstrate exactly how creepy Tesla can be if it really wants to -- he ignited an Internet storm. Some praised him for fighting back against a flawed review, others (me included) scolded him for throwing a public tantrum. Your mileage may vary.
