Everyone’s an expert in two things -- their own job and advertising.  Everyone has a point of view and at a time when we all have a social media presence it’s easy to confuse that with being an expert.  Expertise has unfortunately become devalued; the prevailing sentiment is that my view is as important as the next man’s even if I’m prepared to accept that I know little about the topic in question.  (Tina Brown has a lot to say about this over on recode.)
