Great idea, and quality implementation!

I think the main thing you are missing right now is some seed content.

If I were you, I would start going through each recent search query and adding some content, even a sentence or two.

People are already searching, and you're doing a great job exposing this, now there just needs to be some results, and first-visitors may not be interested in doing the work for it.

I think you're on the right track, and your project has great potential!
