Here’s a neat idea – a Google Earth KML file of geolocated wikipedia articles. As you roam the Earth, see links to relevant articles popup. Might be even better as a dynamic link, so that Google Earth simply requests articles for the field of view, then it could stay updated, but still, a nice concept!
For dynamic link see:
http://www.placeopedia.com/data/
(ok so thats using a different ‘db’)
or
http://www.alder-digital.de/wiki/index.php/Wikipedia_in_GoogleEarth_%28en%29
(linked from the page you posted 😉 – hosted in wikipedia german I beleive weather it autoupdates from teh central db havnt a clue
And I am sure made one with this:
http://www.geonames.org/export/wikipedia-webservice.html#findNearbyWikipedia
but cant find it now… (will make one if cant find it!)
