Interview on ABC News about teens being more & more addicted to Facebook

This link ( http://www.youtube.com/watch?v=62qlXYPDfFc ), talks about how Facebook has been affecting teenagers lives (more often in a negative way than a positive one) since it has been created. Once, teens get to the point of being ''addicted'' to that kind of social network. You can clearly see how that could destroy them at some level. When a teenager spends 4 to 5 hours a day on Facebook (or even more than that in some cases), this person is more likely to get lower grades, spend less time with his family, will be struggling on making new offline friends other than Facebook ones.
