Not even the trees can save you from yourself.....What exactly do you think facebook does? How does a company that has a free product make billions of dollars?
I mean one of us could write an API to scrub four square check ins, facebook updates, even geolocation off certain devices.
Now lets imagine we are the most powerful government in the world. Wouldnt social networking be the FIRST place you would start data mining your citizens?
What would they have to gain by identifying OMG outhouse? Or what happens in his open air hot tub late at night... bible study right?
Something like 60% of Americans use some for of social networking, with the algorithms that government makes (Im basing this off of what advertising companies currently are doing) i bet they could find out just about anything they would need to, with no drones or cameras.
I know what you're thinking though, I dont use facebook or I dont post identifying information. But you have kids, relatives, friends that can identify you. Take it even further and I bet there is a way to tie all your traffic to your name. Potentially all your internet traffic, including from mobile devices is being logged and is tied to your real name. Phone convos are also routinely taped.

And that bit about ratheon is two years old, the tech is so far out of date they can openly talk about it.
