Facebook turns 10 Tuesday. Gazette staff writer Christina Pazzanese interviewed Harvard’s Jonathan L. Zittrain by email about its evolution from an online social directory for Harvard College students to a communications giant worth $135 billion and used by 1.2 billion people. Zittrain is a professor of law at Harvard Law School and the Harvard Kennedy School, and a professor of computer science at the School of Engineering and Applied Sciences. He is also the co-founder of the Berkman Center for Internet & Society.
