Europe will over the next years install a GPS-like positioning system called Galileo. The German list got a suggestion to include coordinates in the form of [[Geo:-13°23'+45°2'23'']] or similar for locations. A future GPS/Galileo PDA/smartphone could then reverse-lookup what wikipedia has about the current location. (This is kind of a PR gag, but still...)
IMHO that brings us back to the map system we already discussed to death ;-)
Seriously, such markup could link to a special page with multiple functions: * Show it on a map * List wikipedia locations nearby and others I can't think of right now.
Should we a) include such a syntax? b) wait for a "real" map system to emerge, or just do this now and convert later?
