Someone must have thought: “What’s cool these days? Flickr, del.icio.us, tagging, folksonomy, Google Maps, RSS, KML, … What if I combined these?” Enter Tagzania. Geotagging using the Google Maps API. Or as they put it:
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.
