Tagzania - Marcación de puntos en GoogleMaps

Tagzania - Tagging the planet: "Tagzania is about tags and places. If you register and log in, you can add places, points, to create and document your maps. When you add a point, you may tag it with keywords. That way, Tagzania is not only a place to build and keep your own maps, shared territories are created as well."
