How often have you been told that you have been sitting with your computer and wasting time doing inconsequential things such as chatting with your boyfriends or girlfriends or generally checking out pages devoted to promotion of films and similar irrelevant stuff on social networking sites? Chances are this has happened to you very often particularly if you are fooling around with the internet and being unproductive at your workplace. But, pause and think about this. You wouldn’t have been reprimanded had you used the free time at your disposal to visit the sites. In fact, even at home, you would have never felt guilty about wasting time because social networking sites can be used for very good reasons.
