Yeah, I don't know whether they would ask that. It's definitely something that entrepreneurs need to ask themselves though. I see too many people running around the Valley like chickens with their heads cut off, getting excited over solutions without a problem. Both technical guys who are so excited about the shiny product they're making and non-technical guys who are convinced that their "vision" is correct. As a technical guy, I don't write a single line of code until I have confirmed that there are actually people with a problem who will pay me for what I'm hawking.
