internet addiction

i am a frequent user of the internet but do not really use it for shopping, dating, or gaming. i know many poeple who are addicted to computer games or facebook. many teenagers constantly post about their lives and whats going on in the world every five minutes on the facebook. i would consider this addiction to a certain extent.  this is sad to me in way, because people get used to expressing their thoughts and feelings online, they forget how to talk to talk and socialize with people in the real world. facebook and other social network addcition can make you shy and awkward in real life.
