Social networking sites are disaster
I believe that social networking sites are unnecessary. Social networking sites may be beneficial due to high sophistication of technology, but was it really worth it? Users may have gained huge advantage, but did you know that there are many witnesses have been victimized? Did you also noticed that social networking sites can leave our identities and our locations exposed? This indicate that sooner or later we may become vulnerable to unknown threats. We didn't ask for this, but still they gave chances for the dirt-bags behind the scenes.
