Total and complete myth;
“Social media activities are associated with several beneficial social activities, including having discussion networks that are more likely to contain people from different backgrounds. For instance, frequent internet users, and those who maintain a blog are much more likely to confide in someone who is of another race. Those who share photos online are more likely to report that they discuss important matters with someone who is a member of another political party.”
So parents, next time you ask your kids to go out and meet real friends instead of spending all their time Facebooking, playing Farmville, Happy Aquarium and the likes, think again.
