BEFORE: "Dad, let's go to the park to play" NOW "Dad, let me AN ACCOUNT ON FACEBOOK" … social networks. What you do not have facebook? Sorry, you are out of this world, only in USA there are 40 million people using the network and in Spain and we are on the 8 million people who use facebook, but … what good are social networks? Let's make a little history: Facebook is a free set up. Pete Cashmore contains valuable tech resources. Originally a place for students, but now is open to anyone with an email account. Users can participate in one or more social networks in relation to their academic status, place of work or geographic region. As founder of the company was announced that Facebook had reached 250 million users.

The same year announced that more than 300 million and already had over 350 million. Marlon Cameron says in an article that contacts mean that everyone has in their account is 120 friends but some people with more than 500 contacts, and even people with more than 1000 contacts. Marlon himself describes all those "friends" are interacting about, taking an average of 120, with more than 15 or 20 which leaves us the question, why people have so many contacts if only interacts with a very small part? One of the reasons that are extracted from the studies is that people take it as a competition where the goal is to have the most "friends / contacts" because these networks may become more friendly to us.
