Social networking sites are disasters. Social networking sites are nothing more than tools for narcissists. Social networking sites are increasing in popularity but are really destroying natural and healthy interpersonal relationships and foster ignorance of the human condition. Take this example, recently two girls fell into a sewer and though they had their cells phones with them, didn't have the common sense to call for help, instead they just updated their Facebook pages until someone figured out they were in trouble and called help for them.
"Yes" is crazy Social networking sites are beneficial? What about all the missing children that go away with their older "lovers" that disguise themselves as young prince charmings? What about bullying that leads to young children committing suicide? Yea, sure that's wonderful! If you want to stay in contact with distant friends, how about writing a letter or making a phone call? It was good enough for your parents and grandparents, what makes you so much better?
