It’s been quite the week for Mark Zuckerberg. On Monday the Facebook founder celebrated his 28th birthday, and on Friday he took his company public. One day later, the Facebook founder and Priscilla Chan wed in Palo Alto, Calif. The ceremony was held in Zuckerberg’s backyard with about 100 guests who all thought they were there to celebrate Chan’s recent graduation from medical school. Contrary to the lovelorn Zuckerberg portrayed in The Social Network, the two have been dating since they met at Harvard nine years ago.
