How old was your kid when you allowed him/her have their own facebook account?

[CJ]

I let my girls have Facebook accounts at 13 and 11. But in order for the 11 year old to have the account we had to lie about her birthday and I thought to myself "what kind of example am I setting if I am lying to get a facebook account?" And what is so important on Facebook to violate my principle of truthfulness? They associate with their friends at school. And yes, there are friends who have moved that they could be in closer communication with through instant pictures and the wall and whatever, but there is email and text. Neither of them have facebook anymore. I don't see the value in it other than it is cool.
