As a person that came from a technical background, I followed the 'built it and they will come' heuristic. It's certainly effective for getting something done and out there. However, I considered nothing about market or even who I thought my users are, or more importantly, where to find them. In this list, I probably would have benefited from the talk to customers bit. Too bad there's no iteration of the business idea in the list. Any of you out there ever get this badge?
