>author of this post refers to himself as a developer.
It doesn't matter what he calls himself. If you can pass FizzBUzz, you're a developer. Maybe not a John Carmack, but a developer nonetheless.
There is no sacred law written on tablets of stone and handed down from volcanic mountains that states "Developers who found startups must code or face eternal damnation." Rather, there is a holy precept that does state "The founder (whether a dev, UX guy or bizev guy) shall find the most efficient path to profitability, or be condemned to the lake of failure."
So if a founder is from a UX background, but in his particular context, it is more efficient (faster to profitability) for him to outsource the UX and read 'MBA for Dummies', I would argue that that is the rational course of action.
Again: Your priorities as a founder are not whatever background you are from. Your priority (and you must accept it :)) is to become profitable. When that is achieved, THEN you can go up the Maslow Heirarchy of business-actualization.
