Interesing read. But I think that better to only talking about your idea to your (candidate)customers you should talk about your product to everywhere, the most feedback you get the better. Of course, you should filter the feedback. I'm in this phase currently, I've been talking with lots of friends, colleagues about an idea and they helped me to polish it, to the extreme that my initial idea and the current version are two completly different products! (But related.) I think Paul wrote an essay about this same topic, but I can't find it :(
