Are social networks eroding our social lives?

According to a recent study by the social discovery site Badoo 40% of Americans socialize more on the internet then in real life. This is a startling figure and it shows that people are becoming more and more dependent on socializing on the computer. I think it is quite pathetic how often you see people constantly looking down on their phones or see people sitting on there computers. Being able to evaluate a person by there expressions is something that is learned by face to face talking and that skill will not be developed if the way you prefer to communicate is just on the computer.
