I'm talking specifically about sites like Facebook or whatever's around by then. Where there are certain risks posed with photo sharing, bullying etc.
And yes bullying goes on without sites but they of course make it far easier, different types of bullying, easier to keep it a secret.
I don't think you need to use something at 12, 13, 14 to be able to handle it at 18, 19, 20. Children are just not responsible enough for certain things, imo, that's why you can't drink, drive, do lots of things until you're 18. Children also just don't need certain things, they see their friends at school everyday, after school, not like adult trying to keep in touch.
I don't doubt it would be much, much more difficult to control what a teenager does, but surely a parent has to up to a point?
Also you can teach your child to use Internet responsibly, but ultimately they are still young and vulnerable, you cannot stop what else is out there.
In none of that is there any concession to what everyone else on the thread is telling you. It is all rhetoric and that's why you got my back up. I'm sorry if you think I'm rude, but I think your attitude to all this is likely to end in a lot of resentment.
