So very true . I live in the US, and my close friends are distributed around the world. My parents live in Africa, my brother is currently in Europe, cousins in Israel, UK, etc, and former colleagues around the world as well. We all manage to stay in touch. Facebook wasn't the first service that allowed everyone to do that, but it's certainly done a better job of getting everyone on. Has it changed the world? Not at the level at which Google did, but it's certainly made it a lot easier to keep in touch with a broad group of people.
