John King has lost his mind on CNN with regard to these touch screens. He just pulled up the positive/negative twitter tracker for the Whitman and Brown election. It showed positive tweets and negative tweets about each candidate throughout the election cycle. The stupid plot was nothing but a mirror image of positive/negative tweets with blips based on big news or proximity to election day. There was absolutely zero useful information from it....yet he decided it was a "fascinating use of social media."
I like King, honestly...but that was just dumb.
