What's my "Disruptive Skill?"

An IEEE newsletter pointed me at a great Harvard Business Review post by Whitney Johnson, that discusses the idea of a "disruptive skill."  Why and how do you beat the competition?  And why is it unique to you?  I'd like to be a cross-pollinator -- a modern day Doc Ricketts, Doc Brown, or Doctor Demento.  Sometimes your *weird* skills are the most valuable.
