But, if it's a really good idea, wouldn't you want to keep it to yourself as opposed to throwing it at other people so they can butcher it for you? And if it's only a mediocre kind of idea, wouldn't'you be best off not inflicting it on the world?

Sorry, I see people running into communities sometimes going GREAT IDEA: IANTO HAS A BIONIC EYE!! and then just buggering off again and I think did you really need to share that with the world?
