Also, the location selection could be a bit more intuitive, I'd maybe make the location name in 'See what's happening in _____' a link to change your location. But overall pretty good, I'll be taking a look at it in the next few weeks :)
Feature suggestion (or feature creep): I think as one other poster mentioned, for people that are in a suburban setting, it might be a neat idea to concatenate search locations: my university, my local city, a local town that i am willing to drive to, and my current position could all be contributors to one "list of interest".
Also love the simple UI. Very Craigslisty. No noise.
