Yeah, I didn't mean it as a knock on the contest... any idea contest could potentially have problems like I mentioned. Guess I meant it just as a warning that it may not work out so great for anyone to post their 'once in a lifetime' idea, as someone else could just say it was their idea too. They'd be better off waiting for a later contest, or just make the thing themselves outside of any contest.

As just a general way to get folks talking about ideas, it's fine though.
