Just spent a few minutes geotagging some of my flickr photos.
It’s pretty cool, you can group photos and place them, or drag a photo on top of another photo already placed on the map to group them in the same place.
Even cooler is that when viewing photos you can click on a photo’s map button and then click “Search for other photos near this one” to see photos taken nearby.
Don’t expect to be able to use any high-res satellite photos of Hobart or Perth to work out where your images were taken though, the highest resolution is about 3 notches above the maximum. [Edit] It turns out that Panoramio offers a similar system but uses Google maps, which are much higher resolution for many corners of the world.
