Great job! This could definitely be useful to find something people already want, especially if you could keep a tally of the most wished for ideas. What did you develop it in?

I also like the logo of the two birds talking. Did you make it yourself, or did you get it from somewhere?

One thing that I see could use a little improvement is the "next" and "previous" links. Right now they just blend in to the background. You should try making them stand out, and maybe make them look a bit more button-like. It would also be worth testing "next" and "previous" links on the top of the content.
