OK gang, here's where I could use some help. I need to research the impact of social networking sites on teens for my Adolescent Psychology class. Some of you are teens. Others have not been a teen in a while.

What I am looking for are articles on the various social networking sources out there. This would include Facebook, MySpace, Twitter, Email, Texting, etc.

Also, I would like to hear your take on social networking as follows:
What systems do you use?
How often do you use it?
What is the main purpose of these systems for you?
What would you do if they were to disappear overnight?
How often do you check your page/source?
Does it interrupt your classes/workday?
