This is such a one sided article. I'm sure that technical co-founders make the exact same mistakes when looking for a co-founder, and the solution would not be "learn to be a business guy, and appreciate the business guy more"

Co-founders are a team and should have complimentary skills. There are far more roles in building a startup that just "idea guy" and "tech guy", so if you are a non tech founder certain that you need a tech founder i would strongly suggest learning other skills that as a team you think you might not possess.

Also asking someone if they know anyhow is not a bad solution to a problem. Maybe it doesn't always work and you have to explore other avenues, but it rarely hurts to ask people as a first move.
