If you think teens aren't using Facebook anymore — that's simply not true. Teens in high school need Facebook, it's no longer a fad social network for us, but it is definitely a needed tool for connecting that we all use.

I saw 13-year old Ruby Karp on CNBC and read her blog post "I'm 13 and none of my friends use Facebook." Her argument is rather convincing: Facebook is not trending in her age group right now, so it's not entertaining for her to go on Facebook. She is right: Facebook is no longer a fad social network.
