Location-based Social Media for Good

While reading the Boston Sunday Globe, I was struck by an article about the lack of maps of the handicapped parking spaces in Boston and Cambridge.  Anything location-oriented seems like a problem that could be solved by one of the location-based social media tools.  Hey, SCVNGR or FourSquare — what do you think?  I would think you could enlist your users to mark all those spots and offer a digital map.  Show us you are about more than just games.
