Summary and response of "Facebook Puts Your Privacy on Parade"

This article starts off talking about Mark Zuckerberg, the founder of Facebook, and how he made a speech talking about privacy changes to Facebook.  The author sums up Zuckerberg's speech saying Facebook made it's users information more easily accessible to other companies.  The author then goes on to say Facebook changed it's privacy settings making it's users more infomation available to the public and made it harder to choose what information they can choose to remain private.  The author then sums up the article saying Facebook is basically selling it's users information to companies and advertisers to make more money off the people that use it.  I think that this is a okay argument.  I felt like the author could have provided some proof of these claims that he makes about Facebook, but overall this article does make you think about your privacy and the dangers of posting certain things on sites like Facebook.
