Ok, I agree that specific ideas have value. However, I think they're not very valuable regardless of quality, because there is little to differentiate a high quality idea from a low quality idea until they are executed. Then your differentiation takes place after-the-fact, making it useless at early stages. If specific ideas are to have specific value, there must be a common method of differentiation. How do you tell the difference between a high quality idea and a terrible one? Finally, if ideas have so much value, how come the market has basically been against the "idea guy", and almost entirely values execution (success = traction, revenue)?
