New Delhi, Dec 18: Let's face it, Facebook has become an indispensable tool to remain in touch with friends, family and relatives and to climb (or fall) upon the inescapable social ladder. On the social networking site, often a short, trivial exchange (e.g. "Hey, 'Yup') can seem pointless, but it's adding to your social presence on the web, as it states to all other visiting users, that this person and you are friends.
Facebook has put a whole new spin to the world of friendship. The virtual friendship world now matters a lot to a lot of people and for those already in a relationship, Facebook is becoming an obsession with who comments or likes what.
Now, researchers from the University of Virginia and the London Business school reveal that the number of friends you have can depend on how successful you are, and even how often you move.
