I would say location weighs heavily on average income as a programmer. For example, the average dev salary in the midwest might be more like $50,000 and anything approaching $100,000 being very high end.
This. Salaries are based upon more than just skills and languages.
It seems like this article is biased towards California or New York salaries. I once jokingly told a SF based recruiter that $55k might not seem too much, but those aren't California dollars, which are worth less than Pittsburgh dollars. If I wanted to make six figures right now, I'd probably move.
