IT WAS December 22, 2008, when I opened my Facebook account at the invitation of Arlyn, a law school classmate. This was more than four years after Mark Zuckerberg and his peers first introduced the online social networking service to their fellow Harvard students. A day after my name and ID photo cropped up in a blue-and-white corner of cyberspace, my cousin Danny Cadorna—whom I had not seen since he left for Japan in 1994—sent me my first-ever friend request. Soon, other relatives, friends, former classmates, coworkers, and even strangers requested to join my friends list. They say that most people who know how to use a computer and the internet have a Facebook profile. Unsurprisingly, in just a short span, my notifications swelled with requests to connect, play games, join groups, and "like" various pages.
