Sorry but this is lame and derivative. Good for you that you made some money but posting it to drive traffic to your site is even worse. I hope that somebody who has powers to do so downvotes you.
I didn't post this to drive traffic to the site, although I am aware that it would be a side effect. The only reason I included the URL is so that the first comments wouldn't all be "what was the site?"
Lame and Derivative: As I mentioned in my previous comment, I don't think it's an amazing idea... it's just an idea. As for derivative, isn't innovation the art of taking old things and reworking them into something new?
