I just received an email from a friend of mine (let's call her Sue) who works at the same law school as another friend of mine (let's call her Angie). I had asked Sue how Angie was doing, and she replied that she never sees much of Angie around the office but Angie is a prolific poster on Facebook and she catches up with her that way. Now, I understand the allure of Facebook and particularly its ability to keep people connected despite geographical differences and otherwise busy lives, but I wondered whether in the absence of Facebook, people like Sue and Angie might have taken more trouble to physically see each other every now and then. In other words, is it possible that Facebook is now replacing physical contact in relationships where people would otherwise have organized to meet face-to-face for lunch or coffee? And, if so, is this a good or a bad thing?
