Editor's Notes
- mapme.at works with various other location sources, including the new Twitter geo features, and basically any service that works with Fireeagle or can output GeoRSS.
- Have always had OSM maps available on the site, from the beginning they’ve often been the best maps of the places I’ve go to.
- Switched to cloudmade maps API partly because they were offering a great product including the Style Editor but also because we liked the idea that by forcing the user to use OSM on the site any location added to the map could be added to OSM later. We’ll come back to this soon.
