I have "inverse aptitude" at knowing what should be a product. :) Never trust me to know what would sell or not. In fact, "bet against whatever I think". ;)

I have "inverse aptitude" at knowing what should be a product. :) Never trust me to know what would sell or not. In fact, "bet against whatever I think". ;) In my ideal (and in the best jobs I've had in the past), someone finds me (or I find someone) who I can share a list of "cool things I've figured out how to do, but don't know the usefulness of", and that person then tells me what to build. For your "where is that annoying sound coming from?" service, what sort of scale do you imagine, and what form factor? A handheld consumer device with a range of ~10m which points in the direction of the loudest thing? How much would you pay for such a device? (would love your thoughts in email)
