Some of the things I heard about how Facebook is getting used in politics to target ads towards people with certain personality is quite scary. Apparently it is worked out from those radio button type surveys that you fill in on facebook. Your answers are apparently tracked against your name and they can work out what sort of personality you have and how you feel about things that are going on. The more surveys you fill in, the more accurate it gets. That info can then be used to create an advert that is targeted towards you that you are more likely to take notice of. It is very clever marketing, but I am not that comfortable with it being used for politics. I do wonder if we would have had the same result, if social media like this wasn't around.
