The people that I usually see getting wowed are web designers and devs, that know the pains of dealing with all those issues that this project is trying to solve. I don't know your background, but if you don't do CSS you probably don't know or care about all the troubles that one has to go through to get your site working correctly across all browsers, laying out your page (most apparent in fluid designs, or with dynamic content from a database), etc.

And again, we would love to hear about how we can market ourselves better, we are all ears!
