Yes we live in a dangerous world, but it is the individual's job to protect themselves, not he admins. The feature should not be removed based on a couple of people not caring.
People could use their real name as a user name too. Should we do away with user names?
I've been surfing the net since I was 14. I have always let my birthday, gender and country be know. Without knowing my real name, the city I live in or any other particulars I don't see what people could do with such little info. A 21 year old female in Canada doesn't get you very far now does it. Now that I live in a really big city I don't mind giving away that info either. A 21 year old female in Toronto doesn't get you much farther.
