Yahoo! Internet Location Platform. As an ex-Yahoo! this is really exciting—WhereOnEarth (a London company acquired by Yahoo! in 2005) provide the incredibly detailed geographical data used by Flickr, Upcoming and FireEagle—and now it’s available as an external API. 12th May 2008, 9:02 pm

Flickr Place IDs. flickr.places.find, flickr.places.resolvePlaceURL and flickr.places.resolvePlaceID combine to provide a really useful, lightweight not-quite-a-geocoder API. It’s a shame you can’t search for places by providing a latitude/longitude point yet. 19th January 2008, 7:34 am
