It's hard. I was on the internet at a very young age but when I was 12 the only website I would go on was neopets

There was no twitter, facebook, youtube, etc, then for me to get messed up with so that made it so much easier. Social networking sites make me kind of uncomfortable so I'd say I would allow them to get a facebook or whatever when they start high school around 15 years old. Call me strict if you want but there's so much cyberbullying and things like that, that go on these sites and it's not good.
