CIA following Twitter, Facebook - Yahoo! News

AP Exclusive: CIA following Twitter, Facebook: "McLEAN, Va. (AP) — In an anonymous industrial park in Virginia, in an unassuming brick building, the CIA is following tweets — up to 5 million a day. At the agency's Open Source Center, a team known affectionately as the "vengeful librarians" also pores over Facebook, newspapers, TV news channels, local radio stations, Internet chat rooms — anything overseas that anyone can access and contribute to openly."
