Location is the most important thing about an apartment in my opinion. That should be the primary method by which you search. And they've tried, but you end up searching within these broad "neighborhoods" in the bigger US cities. And a lot of people mischaracterize their apartment's location in order to make it seem nicer or whatever.

Why is craigslist wasting my time? Require posters to put in the actual address or at least an intersection for their apartment. Then show me the postings on a map. Something like hotpads.com works really well for me, but they don't have the volume that craigslist does, so I'm stuck.
