Sadly, Geobloggers is no more according to Ogle Earth. Perhaps, as someone has hopefully suggested on the Flickr forums, the Geobloggers code could be open-sourced. For those not aware, Geobloggers was a visionary application that located Flickr photos in Google Maps, and later in Google Earth too.
My favourite free alternative to Geobloggers was the GMiF Fire Fox extension which embeds Google Maps into Flickr. I welcome the latest development: Yuan. CC Maps. My geotagged Flickr photographs have a new home! It’s a really simple application that works beautifully, though not with Google Earth (yet?).
Yuan.CC Maps looks like this: (quite a big file)
