I have a general question for you because I have had many ideas that I have tossed aside because I look around the internet and find that someone is already doing it. So, the question is, how do you decide that your idea is different enough? For example, if I had the idea you are describing and I posted it here to have mattnelson point out
DoMyStuff.com - Outsource your life, I would be dropping the idea because in my mind, it has been done.
I am not trying to be a jerk here, I am sincerely asking, how are you deciding that your idea is different, because I don't see it?
Thanks and best of luck.
