Lest we forget, the reason Facebook took off in the first place is Privacy. The design changed every six months or so. Ideas are a dime a dozen. To start a company such as Facebook, you must have an intimate knowledge with how your product works. A 'Hacker' implies that someone knows the internals of their program, a 'Designer' implies they know how to make it look and feel nice. The Hacker mentality works great for leading a company, knowing the ins and outs and possible future situations. The Designer mentality does not, making it look and feel nice. The next Zuckerberg will be a hacker.
