You can't throw a stone in the startup community without hitting a blog post, tweet, or discussion around co-founders. While I think there's a great deal of good advice out there on the search for a co-founder on places like Venture Hacks, Humbled MBA and OnStartups, it's as important to understand the potholes to avoid. Just like a pothole will disable an otherwise great car, these mistakes will derail your company...and your cofounder search.
