So you started developing your idea for a startup, you maybe working alone or along with another co-founder. Of course you are fascinated by your idea, thinking how cool it is, but nevertheless you are still interested in knowing what other people think. So my question is, how to get and process feedback from other people? There are a lot of issues worth considering; for example , the person you're asking the feedback from (you won't ask your 50 yr old dad if he thinks your IPhone photo sharing app is cool.. ) and most importantly, how to process this feedback - how can a founder predict the value of his/hers idea 'neutrally' (asking the right people , of course, people who might use your product)
