I can see reasons why you wouldn't want to share an idea, but I think they are border cases. I've been spending most of my free time for the last couple months building a site specifically for discussing and getting feedback on ideas. I believe there is a lot of value in getting other people's insight. Ideas have a great built in defense- as soon as they leave their owner, they are poisoned by another point of view. No matter if it is repeated, a person's vision for what it could be doesn't transfer, it is intimately personal.
