I expect to see one, and perhaps more, best-seller books written by “insiders” at the two presidential campaigns on how they used (manipulated?) social media (especially Twitter and Facebook) to gather many unexpected votes. There will be heroes who used social media constructively to help encourage all American voters to go to the poll, and those who tried to use social media as a more effective way to perform dirty tricks on the other candidate by untrue character or policy posts (all done via “no cost” advertising).
This is a much more dangerous game than it was in 1972 when Nixon’s campaign staff undermined confidence in the possibly successful presidential campaign of Edmund Muskie. Now just about anyone in the world with a knowledge of how rumors grow overnight in social media can attempt to manipulate campaigns, often for little or no cost. Remember that sometimes that big supporter of a candidate in social media is little more than a very smart troll.
At least one best seller in 2013. My suggested title is “The Troll Who Came Out of the Hole.” It will definitely not be a book for children.
