Can someone tell me what is facebook?

Its a social networking website. Like myspace. I wouldn't sign up. Losts of people's identities are stolen, passwords changed, emails changed, and people say bad things in your name if they can hack into your account (which is simple) its not private at all. The Facebook network can use your information you share with the world. DONT sign up.
