I agree with the underlying message, which is to listen to your market. I just feel that the example Justin used is somewhat unfortunate, because I feel it describes a missed opportunity. Of course the barber doesn't think he needs anything beyond a better paper calendar, but what do his customers think? Would they, perhaps, prefer to book online instead of over the phone? I guess that what I'm trying to say is that you should definitely listen to your customers, but you shouldn't let that blind you. It's like that Henry Ford quote: "If I had asked people what they wanted, they would have said faster horses." The problem, of course, is that very few people are Henry Ford material ;)
