If you're willing to share the idea and it's decent (i.e. people wouldn't roll their eyes at it) let me know and you can contribute it to a website I'm building, receive credit for it, and receive traffic to your site from it. If your site sells a product that compliments the idea (i.e. your idea is a detailed guide on how to blog and earn money off ad revenue and you sell wordpress themes, etc) then this could be very lucrative for you. I won't post the URL to my site because I don't want to violate advertising rules, but if you are interested in contributing to it in exchange for credit and a link, post in this thread and I will send you details.
