Location Voice Tagging

Alright, this is an interesting one. I ran across a service today, Geo Graffiti, that lets its users call a number at any time to tag a given location with comments.

Confused? Consider this...

You're walking down the street in some city and see a really cool art display - think random locations in Seattle or something. You pull out your phone and call Geo Graffiti, which recognizes your number and prompts you to leave a message. Next time you go back to your computer, you see a map of all the places you've been, along with tags in each geographic location that you left one.

Now little voice tags are only so interesting. Imagine a mobile app that can access your camera phone, or the collective effect of a community all tagging in the same city. Or imagine concrete moments in time - like a certain song at a concert - that you could record and forever relive on the web.

After a while, the map becomes your digital journal organized by time, geographic location, or whatever else. Pretty cool way to chronicle your life.
