Should it ever happen that you run out of things to look for in Google Earth, head on over to earthsearch.net, which has a browsable index of over 5 million “features”, listed by name country, type, latitude and longitude. (Okay, so there’s duplicates, but still.)
Many of these Google will find for you if you just type the name, comma, country into Google Earth’s search field (or use yubnub), but for those that it doesn’t recognize, there’s always coordinates. (A script that opens highlighted coordinates in Google Earth sounds like a great idea. Even better, perhaps, would be a script that searches earthsearch.net if Google Earth comes up blank)
If you use earthsearch.net’s own map to zoom in on a feature, you also get a list of nearby features along the side. That functionality — and this entire site — is just begging to be turned into a monster of a dynamically updated network link.
