If I were the NSA I'd open a VPN service. Of course, I wouldn't call it something like "NSA VPN" - I'd be sneaky. I'd pick a cool name - something that wouldn't be suspected. I'd set up a website, tell everyone I was somewhere really neutral, somewhere that sounds safe. Hell, I might even really base myself there. Then I'd do a write up about how dedicated I was to privacy. I'd probably make myself sound like a cool hippy character and someone that was a million miles from a "man in black". I'd make it sound really good and convincing. I'd tell everyone that I didn't keep logs and that I was well outside the jurisdiction of the USA. Then I wouldn't need to weed out the good stuff from the billions of boring facebook postings - the privacy conscious and those who really had something to hide would be self-declaring by signing up to my service. I wouldn't need to find them - they'd come to me. Hell, they'd even be paying me for the service. Then I could really access the interesting stuff (& the boring privacy people - but frankly they wouldn't interest me) without having to spend loads of time weeding out the chaff. Good job the NSA aren't sneaky. Or are they? Best trust no one!
