Similarly, I have rarely met an SEO or social media expert who wasn't full of shit, and I have to deal with these people on a regular basis.

I've read reports with analyses that were blatantly wrong from a statistic or technical perspective, I've had discussions about the value of 'meta keywords' and whatnot where google itself refuted their arguments. And the most 'effective' experts I found were only so because they'd do all sorts of shady things like set up blogs for link juice.

On the other hand, I have met plenty of people with deep knowledge of SEO and social media, but very few of them called themselves primarily experts in this area. Usually they'd be web developers/designers, or small creative studios, or just have some unsexy job description working for a big company.
