Honestly the biggest chock should not be that Keith Alexander (NSA) is a horny bastard for private data, or whores like Zuckerberg (FB) and Larry Page (GOOG) bending over for NSA.
The issue is how foolishly we internet users share so much private data without considering the risk of the data getting in to the wrong hands.
What facebook really is about for NSA, what they care about:
-WHO: getting info about each individuals social network, they know exactly who you know.
-WHERE: knowing where you are every day (every time you login to FB the GPS/IP data is logged). Some idiots even report themselves with "Check In".
-WHAT: searching for keywords used in your status updates, or private messages.
-BONUS: getting info about people that are smart enough to not be members of FB. But info about them might end up at FB when they are in pictures that you upload.
"Report themselves", lol that's great. I really do find it stupid that people feel the need to publish every detail of their lives and what they are doing as each and every day goes on. The total depth of this crap is show in exhibit A below:
"John Doe is at the car wash"
"Michelle Q. - I'm @ McDonald's yaaay
"
"Mike M. - Taking a huge shit right now at my house!!!"
Pointless, unintelligible garbage.
