A website owned by the CIA used to spy on dumbasses who do all the work for "big brother". Appeals to brainwashed tools who are stupid enought to be concerned with fashion and trend and sports so getting them to fall for facebook and twitter and cellphones isn't that hard.
Sign up for facebook and let the US government know exactly what you're up to at all times! Remember to use your real name! And get used to all that farming! Once the Bilderbergs take over all you're going to have is dirt.
