Is there any evidence that Mark Zuckerberg has any actual foresight or insight on privacy, security or Facebook as a product? If so, it never seems to be evident from outside the company when he needs to present himself. All televised interviews of him shows a person who seems to lack any deep knowledge of the issues, the long term consequences of his decisions or strategic planning. Based upon this (lack of) evidence, I increasingly think he was simply in the right place at the right time and hired good people to steer the company to where it has succeeded. In the end, Facebook's success is probably more due to people like Sheryl Sandberg. There seems to be a long-term Facebook PR strategy of keeping Mark out of the limelight so his incompetence isn't on display.
