Please review my views on Social Networks!

I want to write something about social networks which are so common these days on internet. I have also made my account on one of the famous social network which claims that it connects people though I am in totally disagreement with this. So many people are there in my friendlist with whom I met hardly twice or thrice and now I have no hope that I would meet them again and even I don't have any desire to meet them. When a huge gap come between you and these so called friends then you start feeling hesitation in sharing your hapinesses and sorrows with them. I have had some worst experiences as well while using it. I think the best way to be in touch with your close friends is through cell phones or through e-mails.
