To be brief, as the chair has asked, I have three children over the age of 12, and in many ways it's the same debate we've had as parents for eternity: how do you learn to control people who are becoming young adults, whether it's online or offline?
But you're right, there's a clear need to provide tools both for young people as well as their parents, to understand the tools they are using, the environment in which they are using, and the benefits and the costs of how to use them.
I mentioned in my notes that Google+ was built specifically with this conundrum in mind, trying to provide a tool for young adults that allows them to communicate but within an environment that reflects that they may not necessarily fully understand the impact of what they're about to do, and also trying to isolate them a bit from those larger societal impacts of their engagement online.
