The moment is finally here: Facebook, the world's most dominant social network with 900 million-plus users, is finally ready to make its Wall Street debut. The Menlo Park, Calif.-based company has experienced plenty of controversy throughout its first eight years of existence, from the Winklevoss lawsuit to questionable redesigns and privacy breaches to hoodiegate, and yet, Mark Zuckerberg's social experiment continues to attract users and investors.
