The article isn't very good but it does raise an interesting question.

What happens when your prospective customers say they would buy your solution if it was available, so you build it, but it turns out there is a big gap between saying they want it and actually buying it.

I see this happen a lot. This is why its probably better to ask for a deposit when somebody says they want your unbuilt product. You will get a much more honest answer.

I also took some sales coaching, it helped me a lot.
