Strange, this is almost like what I thought pvsh should be (http://news.ycombinator.com/item?id=4867883) -- you're connecting people who want things with people who are making them. Except instead of letting people generate ideas for entrepreneurs to jump on, you're asking entrepreneurs to lift their skirt before they're ready for the dance. Also, you don't have the monetization I'd expect (or at least you're not talking about it yet).

Edit: I just realized that "If you sign up now, you’ll get to submit your first idea free" implies you're monetizing the entrepreneurs who use the site -- so all content is paid content.
