Azeroth the Google Maps way

MapWoW is a nifty site which uses the Google Maps API to let you zoom and pan from Ashenvale to Zul'Gurub. While maps of WoW aren't rare, the depth of this one seems to have taken the Internet by storm, with sites from Slashdot to Fark covering it. I usually find the in-game maps suffice, but when they're not up to scratch, this should do the trick nicely.
