Folksonomies and Google Maps?

Add another one to the earlier post: FoundCity. Foundcity lets folks “tag” physical objects in a database and displays the locations of the objects on a Map so that others can find them. Like the others, uses Google Maps.

The number of applications for Google Maps must be astoundingly high. And, since these interfaces are being created by individuals and at such an amazing rate, it must be pretty easy to tie into the API.
