This title seems like I've written it before. I know for sure it's an idea I've been playing with for awhile, but I get distracted with other geo-projects *so* easily. :)
GeoBloggers searches the Flickr site for 'geocoded' images with GPS position in the Exif data or geo:lat=53.013, geo:lon=-2.175, geotagged
tags in the Flickr tags. It then displays these on a stand-alone version of the GoogleMaps.
Very slick, very simple, very effective.
