Facebook has made its initial public offering aiming for 5 billion dollars in shares to be sold this spring when the company goes public. A letter to the shareholder from Mr. Zuckerburg himself states "Facebook was not originally created to be a company. It was built to accomplish a social mission — to make the world more open and connected." With 845 million monthly active users it is as of right now the number 2 most visited site in the world (right underneath Google).
