Is (insert idea here) a good business/app/website idea? Would you pay (amount) for (product/app/service)? Do you like my app? (web/iOS only, for now) Does my landing page look professsional? Getting one guy's opinion about any of these things is anecdotal at best. It's not a comprehensive information source. And it would be foolish to use it in your decision making process. There's better ways to collect data: 1) Spend that $10 towards an adword campaign for a pre-launch signup page for you website/app idea. Maybe this guy won't sign up, but maybe a dozen, a hundred or a thousand other people will. Why waste your money on one data point? 2) Put the money to buying beer. Invite your friends and family over, get them liquored up a bit. I guarantee you'll hear a great deal of honest feedback. 3) Post on HN, reddit, slashdot or any other number of web sites where armchair cynics freely administer scathing advice.
