Ideas aren't as sacred as you'd think. It's the execution of them that generates revenue.

You are underestimating ideas.While I do agree with you in 80%-90% of cases, there are still excellent ideas that should stay under the radar.If you don't execute an idea doesn't mean it worths nothing.It means you don't harness it's power.It's kind of the same as having 1 ton of gold in your garage and keeping it there.
