My favourite page in Internet

I´m not fanatic in Internet, I don´t like to be in front of computer all the time. But, actually is necessary use Internet, specially the social networking, overcoat if study in the University for search information, download annotation and talk with class mate.
For this I use the web page Facebook. Facebook is a web page that has numerous users in the world. In this web page is possible show pictures, music, annotation, opinions, feelings, etc., as well as of talk with friends. I use the Facebook principally for talk with class mate, too I can talk with my friends when I can´t see face to face or when my phone is without money. Is a way quick of communication.
Too I like Facebook because has privacy settings. I begin use Facebook in the year 2008, in the 2009 I had like 600 friends en Facebook that in the real life were unknown persons, is terrible! I decided deleted friends, later I had 200 friends. Too I used the privacy settings, now only my friends can see my pictures and publications, for luck. For me is very important this, because I´m introverted.
Actually I see my Facebook in my cell phone, is very confortable, and of this may I avoid to be in front of computer.
