I feel slightly saddened parents and children are taught that the internet is a completely unsafe arena in which your only chance of survival is to never give out your name or any details about yourself and to never talk to strangers.
For kids who don't know better, this is perfectly fine. But, let the teens at least decide for themselves who they can and cannot talk to.
It's a wonderful learning experience that develops skills useful in the real world too.
It's simple to us, but it takes years of experience on the Internet to know what's what. I don't blame parents for not knowing.
