Google has started a new blog focusing on Google Earth, Maps, Local and APIs. Lat Long Blog will chronicle Google's efforts to build the "geoweb," according to John Hanke, director of Google Earth & Maps.
I don't think that there is agreement on what the geoweb is, but I think there is a lot of enthusiasm and energy across many fronts to make it happen. I expect the "it" will evolve substantially over the next few months and years as we (the geo ecosystem on the web) collectively figure out how "earth browsers," embedded maps, local search, geo-tagged photos, blogs, the traditional GIS world, wikis, and other user-generated geo content all interrelate.
Google's geo products and services include the My Maps custom mapping features of Google Maps, as well as geo searches, which surface user-created geographic information in local searches in Google Maps and Google Earth. The blog cites two examples of geo searches: windsurfing near San Francisco and Jerry Seinfeld in NY.
