To Facebook or Not to Facebook

I have been using Facebook for a while now and have begun to notice that all the ads on the side of the webpage are stuff I like to do or that I am interested in.  This just proves what the article talked about, that Facebook is selling away our information to companies and corporations.  It is a cruel way of making profit.  Our personal info, such as what we search and do on the internet, should be kept safe, not thrown out to the world.  I feel that Facebook just uses us in this way, but alas, it is a useful tool in keeping people connected over long distances and allows us to continue our social lives outside of school/work.  This is why I continue to use Facebook.
