The U.S. Central Intelligence Agency has a crack group of analysts tracking the Internet, including tweets and Facebook messages, that takes the pulse of the world. Located in McLean, Virginia analysts at the CIA Open Source Center are known as the "vengeful librarians" according to a report from the Associated Press. These librarians are tracking up to five million tweets a day from places like China, Pakistan and Egypt.
It is sometimes disconcerting to know what the U.S. intelligence complex is doing, right in your backyard. McLean is a beltway city in Northern Virginia that is best known for Tysons Corner, one of the shopping hubs of the East Coast. On the outskirts of the city limits there is also the George H.W. Bush CIA complex, on of the agency's main hubs in the D.C. region.
