Graticule and MapQuest?
MapQuest has sent out several emails about their current geocoding API being discontinued. Here is the latest:
Graticule, a ruby wrapper around many popular geocoding APIs, uses the old MapQuest API. I don’t use it, and I don’t know if anyone else does, so I’m leaving it to you, lazyweb: If you use the MapQuest API, or want to in the future, fork graticule on GitHub and update the MapQuest wrapper.
