Comment 5 for bug 524013

How about using a service like Geohack (which wikipedia uses).

e.g. http://en.wikipedia.org/wiki/Millbank_Tower has a link at the top
"Coordinates: 51°29′32.0″N 0°07′33.5″W" which links to:-

http://toolserver.org/~geohack/geohack.php?pagename=Millbank_Tower&params=51_29_32.0_N_0_07_33.5_W_type:landmark_scale:3000

Which lets the user choose which mapping service to use.

If people can discover the Lat/Long of the location of their event (this is trival to do) then we could hold that in the database and generate the above geohack url to present a decent page to them?
