Well, here’s something interesting. There’s one social network on this planet, for which you don’t have to signup to. Even if you think you’re not on any social network, everything, right from the time you spend in a particular location everyday to the companion who accompanies you to the office, the social network created by NSA has it.
According to the New York Times, the United States’ National Security Agency has managed to gain information about a lot of Americans, and have stored a lot data from a lot of different social graphs, which includes social networks like Facebook.
NYT also reveals that NSA changed its policy to help them discover and track the connections between intelligence targets overseas and the citizens in the United States. The new policy change has been happening since January 2011, and is still going strong.
