The man who founded the company in his Harvard dorm room in 2004 is now its CEO, chairman of the board and controlling shareholder. In its regulatory filing, Facebook credits Mr. Zuckerberg with the vision to create what has become the largest social network on Earth. But as Facebook changes into a public company, its 27-year-old founder will still have final say over all major decisions, largely unchallengeable by investors or the board of directors. In my study of organizational behaviour, I have yet to come across one who was considered great who did not also have a significant body count of ex-employees claiming that they were autocratic and mean. Examples include Jack Welch, Steve Jobs, Bill Gates, and Larry Ellison. My theory is that the level of personal demanding needed to drive a global enterprise to a position of world-changing leadership is one that can be too much for some people. Such leaders do not tend to provide much in the way of emotional coddling and Mark Zuckerberg is like that. If your confidence in your own abilities is self-generated and emotionally secure, and you are seeking someone who will pose to you ever-greater challenges to surmount, then Mark Zuckerberg is a pretty good fit for you. However, he is not there to develop you because that is your own job. Following Facebook's initial public offering, Mr. Zuckerberg will continue to own the majority of the company's voting shares. He will also own the largest single stake of the company as a whole. Even though Facebook has brought on more experienced business and technology leaders as the company has grown, Mr. Zuckerbeg is the youngest member of the board, by about a decade and it is unclear how much influence they will have over the man who founded the company. Since he founded Facebook eight years ago in a Harvard dorm room, Zuckerberg has methodically consolidated his control
