Internet.

I counted 178 "Social networking Websites" on Wikipedia.org. Majority of the sites listed, I did not know. I chose to research faces.com. Faces.com is a social networking site started for British teens. The goal for this website was to encourage online interaction.
I most frequently use Facebook and Myspace. An incident where a social networking site has helped me was when I found my long, lost, half sister on Myspace. I hadn't met her before, so her contacting me on Myspace was super exciting. That was probably one of the only times a social networking site has ever helped me, though. Ha Ha majority of the time they're just drama.
