How I use facebook

At the beginning I was suspicious. People were starting to use facebook and it was really strange to give so much personal information away in a public page on the internet, I heard somewhere that the tool, the social network was invented by the CIA and if you think about it is an exellent tool to control us and know all about our lives. So I refused to go into the network and laughed a little at the people who would go and voluntarily upload to internet all of their personal information, giving them self away to the police!
But then a couple of really good friends of mine who recently when away to study in Argentina started to ask me to go into the network, they say: you can only give the information that you want to, it can be false, and you can chat to people, share different contents as pictures, videos, etc. It will be like seing each other in person, and I insisted on sending them mails, they never wrote back...
So one day I make one, but just to talk with these two persons, and we talked, now I look back and think we talk the same that when we wrote each other e-mails: not much. But I get to see pictures and feel like I'm participating a little in their lives.
When I was already in, of course started to appear many people who would like to be my friend on facebook, at the beginning a didn't accept any of them but finally I fell into it.
Is demanding because when you are online is in a way to be present in some kind of space when you are surrounded by your friends, and you get to look at their stuff but you don't have to expose yourself in any moment so is a mask, you get couragius. Also and the most important now a days is that is a real good place to talk about job or to show your work.
