Thx -- in my experience it really takes a week to get into it. If you can stick it out I'd love to get your additional feedback after that point.

Point of fact: it isn't MapQuest, it is OpenStreetMap served via OpenMapquest, which uses their resources to forward that project. You can read more about it at http://openstreetmap.com/ (left column) and http://open.mapquestapi.com/ - in any case, maps are relatively new and in process.
