The current flaps of Government agencies using social media to send out messaging on monitor users is no surprise. After all people willingly shared the deepest thoughts on a "public" platform and abrogated their limited right of privacy, if any even exists.
But alas that is just the tip of the iceberg. This medium allows for total psychological profiling as well as using that information to prime people to respond in a certain manner. Think Manchurian Candidate and use smart phones instead of the ladies garden club.
Namely one can readily find individuals who meet a certain psychological profile and then send them messages to effect their behavior, if not totally control it. This is a powerful and dangerous tool. The type of tool which should be delimited. Instead the Government is wallowing in its swamp and one can only guess how far this will go. It further opens up the path for many others to do the same.
One wonders if we should just let some of these creature go back to writing on rest room walls.
