Facebook is using you

Today I have read an article called Facebook is using you by Lori Andrews. The topic of this article is about  you watching yourself when your are posting  and searching on Facebook, twitter, myspace and so many other websites. When you pick like your favorite books, activities and what college you want to go to on facebook, ads that goes with the topic will pop or be on the side of your profile. For example, if you say you like Abercrombie & Fitch, Abercrombie & Fitch advertisements would come up and you can click on it or not but it will take you straight to the website. The main thing that had me shocked was that people can see your searching and the data that you have. As I am writing now they can see what I am doing. That is uncomfortable to me and maybe to many other people. That is basiclly invading your privacy and invading your personal information and so many other things.  The cookies in your computer is another thing about the advertisements. A cookie is a information storer that stores what you searched and shows advertisements  of what you like. In other country's it is different. They are not aloud to look at your data without your permission or unless you know. To me they should put that in all countries to give people privacy. Definetly in the United States of America. What is the point of looking at people data. This should stop immediately and changed to where you can't see the data like all the other country's.
