"Sumaato" have developed a ridiculously slick bookmarklet that uses the Google Maps API to allow even easier Flickr geotagging. A sweet feature made better by using Google's better maps ('specially for Japan ;)
Seriously. Look at this photo of the Torii in the Bay (Miyajima), or the Hotel in Hiroshima that survived the blast, or Daibutsu, the big buddha in Kamakura. I had no idea precisely where I was when I took these photos. Now I do. (the fact that I can find them on satellite photos is a combination of good sense of orientation, memory and patience ;)
Oh and this announcement--"Nokia acquires gate5 to add robust mapping and navigation to its devices"--can't be terrible either.
