To them I have only this to say: Stop please! A recent article in theWall Street Journalblamed Facebook's ability to ruin friendships, saying that it limits communication to typing and encourages people to spend far too much time with friends they have never met. Having used Facebook since its first year, I find these arguments false. The simple truth is that the problems are only a symptom of Facebook abuse. Like many things, it is only as harmful to your life and relationships as you allow it to be. Consider arguments against watching too much TV and overeating. Try using Facebook to find friends who may have long ago changed their e-mail addresses and phone numbers, to find out what your old college friends are up to, to congratulate your friends on their latest birthdays, to share pictures and articles you find interesting, and to join in the discussion about them with your friends.

If you tire of my personal updates, ignore them. If you don't want to join in the popular online games, don't. It is a fun tool at your fingers that can be used for both good and bad. If you don't like using Facebook, don't. I am now a consultant at the Department of State. I use Facebook to keep in touch with friends, family, and colleagues who live and work all over the world.
