Crowdsourcing is THE Competitive Advantage

The idea of crowdsourcing is like outsourcing, but with your users. If you’re smart about it, you can leverage your crowd as a significant competitive advantage. I could easily use YouTube as an example of how their audience is a core component of what makes them as big as they are, arguably more so than anything else, but that example is obvious. I want two use two examples that may not be as relevant, and two products that are relatively brand new in their extremely competitive categories: the iPhone, and a game for the Playstation 3 called Little Big Planet.
