As I say on the google+ page Facebook is like meeting friends for coffee at a virtual coffee shop. I communicate with people all over the world through Facebook, I live in Singapore and am often talking with people in India, Germany, Japan, Australia, the US, UK, all over. Indeed Facebook makes the world a smaller place. Facebook notifications appear quite often, several red dots on the menu. Notification are easily turned on and off while keeping the person as a friend, you can always look at a friends Facebook timeline rather than receive notifications for all of their activity.
