“Do you have Facebook?” I remember that question from many old friends. My best answer is “No, I don’t.” Some of them laughing and did not believe that I don’t have it. “Come on, make one,” that they general advice for me. When I told them that Facebook only waste my time and useless, they laugh loudly and called me old fashion man. Is it wrong if I don’t have a Facebook?

Social network is like contaminated diseases. Few years ago, people use the Friendster, yesterday is own a blog, and today are Facebook, Tweeter, and others. What about tomorrow? What about after Facebook? Some people thought that having a Facebook is necessary, but for others is stupidity. Social network is effective for some people who use it wisely. In other side, it is waste your time, exhausted your vital energy for good works, and makes your computer or phone as “garbage” of some nonsense words.

Above of all, social network is a huge business, Mark Zuckerberg the CEO and co-founder of Facebook is youngest billionaire today. He laugh loudly and wrote, “I am a CEO, b**ch!” in his business card when begun Facebook.
