"For example, SEO is not a black art, it is well documented." SEO takes a different kind of person. I do both (software design and SEO/marketing) and am pretty successful at it. However, pretty much all developers I know despise anything related to marketing, are really bad at it, or just aren't willing to spend the time learning it. It's also not "well documented". It's like trying to say that investing in the stock market is "well documented".
