Online communities have become a form of communication between people who know each other in real life and help us to find new friends, and also a way of meeting people that we know only on line. Today relationships have a lot of meaning. Relationship can be between parent and child, friends, relatives, neighborhoods and people who work together, who has own business . Nowadays it might seem like a hasty generalization, but all people use social software, including text-based chat rooms and forums. They use it to know all information about friends lives; they can easily visit their account and connect. I wanted to find the answers to some simple questions - just how usually do people use special programs such as Facebook and Skype, how this affects them culturally and economically? Then, how has online shopping changed relationships, what are the advantages of social networks.
