How can I make PadMapper.com better?
PaddyTheMapper: And, to get a comment on the board: 
Some of the features I'm planning on adding, once I figure out an unobtrusive and usable way to do them: a favorites list, neighborhood crime rate overlay, probably a more details page with a list of nearby businesses and some other things, and full text search filter on the listings. Driving commute time filter is also a possibility, but only after I expand the subway commute filter coverage to more cities.
