I've started Geoblogging... which is putting the latitude and longitude into tags on Flickr photos, which is then combined with Google Maps to give you a map with the location of photos. It's very cool and it's something that I think should be more integrated into Flickr... the same as the date and time. It's very cool and you can see the map of my photos which will update as I add more pictures. A very cool example of the neat things you can do with information that is shared.
