Facebook boasts that its users upload an average of 300 million photos per day, and its servers contain more than 100 billion photos. And that's not counting third-party applications that also hold photos, such as the .

Facebook controls our privacy. I know what you're thinking -- we control our privacy, to a certain extent...don't we? Well, yes, but many of us have given almost complete control of that privacy over to Facebook.

Sure, I can adjust my Facebook settings so that only my friends can see what I write on my Facebook wall, or only my family can see my date of birth, hometown, and phone number. But I did put all of those things on Facebook to begin with -- and my "privacy" hinges on Facebook's "promise" that it will protect that privacy. Had I not put any of those revealing details about my life on Facebook, I would retain control over my privacy.
