Below is a quote from http://www.paulgraham.com/startupmistakes.html:<p>"But as Larry and Sergey found, there's not much of a market for ideas. No one trusts an idea till you embody it in a product and use that to grow a user base. Then they'll pay big time."<p>Do you think that statement is still true? If so, what about openinvo or any number of other sites that are trying create a market place for ideas?
