Also, the long history of business, and the recent history of crowdsourcing, both suggest that it's always possible for customers to think of ideas that hadn't been considered (or considered properly) by the businesses they patronize. Take Starbucks' MyStarbucksIdea.com, for example. This isn't a dig on business, just a testament to the power of distributed thinking.
Of course, most of the crowd you're sourcing is going "um, I don't like this idea".
