Just asking in passing will mean they have to digest that app very quickly and then try to make a decision. So that's not really surprising. I found more benefit just focusing on problems, like "What annoys you at work related to your job"? Unless they just can't articulate, you quickly find things to latch onto where a technical product (software, hardware, whatever) might help and you go into more detail with them. The goal is really finding under-served markets, which I think what the article says to do, because products seem pretty straight-forward once you know those problems exist.
