Flickr has just launched a geotagging feature that is integrated with Yahoo Maps. If you have a Flickr account, you can go into the Organize section when you are logged in and there is a new tab "Map" where you can drag and drop your photos onto the map. It's kinda like Frappr.
To look at the map of what people have tagged you just go to http://flickr.com/map
I've put my photos from San Clemente up. Just search for "San Clemente, CA." If you aren't familar with the city the tunnel, Carrow's, and the high school are all close together near the intersection of Interstate 5 and Avenida Pico. I also put a few up from around town like the shopping center, Sarmentoso/Del Rio, and where Dode gives Emily the note. Oh, once you've got San Clemente in view on the map, search again for the "Brick" tag and my pics will stand out and you'll have to zoom in all the way and switch to satellite view to see it in detail.
