See this Washington Post artcle -- http://apps.washingtonpost.com/g/page/national/how-the-nsa-is-tracking-people-right-now/634/

This is why social science research education should be part of a well-rounded college degree. Knowledge is power, and power should not be concentrated in too few hands.
Get your degree rounded (and learn THIS VERY TECHNIQUE while you're at it) with our very own Social Networks course, SOC 375, offered Spring 2014 at the University of Maine at Augusta -- http://uma.edu/
