To Facebook or Not To Facebook

At first I thought that Facebook was a way for people to socialize and find people they once knew.  Of course this is true, but there is more to Facebook then what is seen on the surface.  There are risks to using Facebook like strangers reading posts, lurkers, and Facebook selling your information.  Facebook's privacy settings are atrocious and won't help anyone hide information.  It is now to my understanding that my information is being sold to corporations after today's discussion.
