Fool's World Map: "This is a project visualizing the world map which many fools in the world imagine. If you can see this map comfortably, you are definitely a fool." The creator updates and reformats the malleable map based completely on capricious, erroneous geographical inconsistencies found within oblvious statements from his comment logs. Examples: (095. Upper right side of Germany became Australia due to a posting by another stupid American thinking "Australia is beside Germany.") and (001. Due to a Texan who thinks "Japan is accessible from Texas by car", Japan and Texas is land-attached."). He also has a page of user-submitted maps, where he encourages you to create your own global eyesore and send it to him.
In the long tradition of Google anouncements may I present to you Google Location search (which if you recall was the winner of the competition they held last year)
Odden's Bookmarks: The Fascinating World of Maps and Mapping.
The ThreeRing Web Mapping project adds a dot to a blank canvas showing your geographic location (or that of your ISP, as best it can guess based on your IP address). They've also got a code snippet to put on your own site that automagically adds your visitors to the map. The US is already clearly defined, Europe is getting there, and Oceania is coming into view. (They've also got one of them Tag-Board thingies, which is painful to read for any length of time.)
