Neat idea... 2 things:

1) When I change location In more options while I already have search results for manhattan (Im assuming thats default) it fails to load/is stuck in a loop.

2) The twitter bar on the right side is too far down on the side and elongates your page. I dont believe this is intentional though because it doesnt look good. (screenshot: http://pexelu.com/Untitled.png)
