There’s quite a few services out there that rely on ‘tagging’ bits of information for searching, indexing and organising (del.icio.us, technorati and flickr to name a few). But recently I’ve noticed a few websites that are making use of tagging to tie information to specific geographical locations. Flickr is the latest one to catch my eye as I can now drag and drop my photos onto a map (similar to google maps) to show where they were taken!
Now imagine the power of searching for a particular thing in a particular location and seeing the results! A lot of fun could be had with this (and of course, a lot of mischief), and there are even more powerful photo-tagging tools out there too!

Personally, I haven’t (yet) got the time to go through hundreds of photos and geotag them all, but it could become a very useful idea for future images I upload.
