social networking

does social networking eg face booking decreases the face to face contact? that question  had me thinking... it is soooo true.. i realized that most individual become addicted to this face book site ( including myself).. instead of being out with friends we want to be on fb commenting on each other wall.. n it seems as if we have a better communication on face book than face to face... as we all look at this and observe it well... we will realize that most people we get to knw is because of these social networks
