My perspective, mostly on UX issues: The splash page has weird workflow- the only way to go somewhere is by clicking on the tiny red dot and then clicking the button. At the very least increase the click radius for the red button, ideally add an on hover that shows where is (eg San Francisco) and have the button click take them there.. Also, clicking on the states feels like it should do something, since the cursor is the "pointer hand" but it does nothing except change the location hash and make it harder for me to click the back button. As for the bar view- graceful loading of page elements would be a big help. It took more than 6 seconds for me to load the content on first load, and it takes a fair amount of time to load between the tabs. I suggest some sort of spinny thing that acknowledges the waiting process as something to help stop me from closing the tab right then and there. (I just took a look at what's making it so slow- it looks like you're pulling down >50 tiny individual pngs- you should probably squish that into a much smaller number of sprites, also same goes for putting all your jquery stuff into one file) That's really what strikes me most about it right now- usually if a page doesn't load within a second or so for me, you're going to have a hard time convincing me to come back to it, and it would be a shame if all the work you have clearly put into a decent idea is negated by a slow ui.
