although the information given is too relevant...but i think too much should be done specially in the area of privacy and security......now a days emails r pilling up with friends request,many of wh. u donot know ..there r instances when in the garb of the name of ur friends someone send u requests to fetch some information about u......these networking site is to meet identical mind of people,or people have same interests to express ur views or opinion and not a place to share too personal talks......
