Don't like how Facebook is run? Who cares? You don't have a vote. Facebook has two classes of stock. The ones the company is selling the public only get one vote each on matters such as who should be on the company's board of directors, executive pay packages and company bylaws. The ones Zuckerberg is keeping for himself and his early investors get 10 votes. The result: After the IPO, Zuckerberg will own 18% of the shares, but control 57% of the votes.
