I might be off base, but I read this thread as saying: "I have an idea that I think is worth a lot of money, but I don't have the [time|skills] to complete it myself. I want to find as few other people as possible to make the idea a reality so that I can profit while sharing the rewards with only one other person.". If this were really about just getting the idea out there and seeing it thrive, you would just come out and release the idea to the world. Some people who look at it might not do much, and some might give it wings. The only benefit of hiding it (with just one other person) is the expectation of personal gain that may not accrue if many people could start-up the idea on their own. I apologize if this is wrong or sounds overly cynical.
I am not looking for money. i just want to see it be created. So while Im working on other things I can look at that and say...nice, somebody did it, and it didnt just disappear into the void...
