Geotagging and Google Maps

This is way cool: Google Maps API now supports a wide array of geotagged sites. In the example given in the link, a properly geotagged Wikipedia article will display a link on Google Maps at that site. Very nice! I expect to see a lot of organizations tagging projects or sites of interest in this fashion. Think about the Nature Conservancy tagging potential new acquisitions or a local chamber of commerce highlighting attractions in their town this way.
