Survey: What do you know about "cyber bullying"?

When I was growing up, high school was so btchy and gossipy. I worry that the advent of social networking sites like Myspace and Facebook could create some really uncomfortable or hurtful situations for young people who are getting picked on, that no one of my generation had to worry about when we were growing up. And that if someone is having a hard time, then maybe this factor makes things even harder. There's lots of young people on Y!A (I'm 28, so I mean people in their "tweens" and teens). Do you have any stories about or thoughts on this issue? Curious.
