Here is actually what Facebook truth about Social Networking. Here is a chart showing how and who people are following you on facebook to keep in touch. Large number of people who follows you on facebook are those you hated in High school, in college and even mostly are you ex and current colleagues at work. And only fraction of friends are those who actually are your friends.
So why would anyone want to be on facebook. If so many people are there who hates you or you do hate them. I would suggest all of you not to use facebook at all…..
