But kids who don't have positive real-world relationships will use online social communities to find those kinds of relationships. They're more vulnerable to the dangers present there.

They are more likely to do things online than they would in the real world. It's the 'You can't see me, I can't see you phenomenon.' There's a perception of invisibility.

We are seeing online social norms that support really irresponsible communication. Kids think that on the Internet 'I have free speech and I have the right to say what I want without regard to the harm it may cause,' which is obviously not true and is a message that parents need to get across to children.

In Jenny Offill's remarkable first novel, 'Last Things,' 7-year-old Grace Davitt watches her mother, Anna, descend into madness and tries to make sense of the claustrophobic world that Anna has created for her.

A bunch of us just saw a need. It's really all about teaching kids to develop positive relationships.

I think there are enough opportunities. We're thinking fairly positively that our kids will do okay.
