ASk HN:Please review my instant map search web app.....

I've posted this for the 3rd time and I haven't received any feedback since I made some changes. I made a big change on the layout, and some of the functionality of my app. Is the goal of the site clear to you? Am I really doing some improvements(for people that reviewed this b4)? Is it by chance useful for you? Thank once again in advance.
