In case you weren't aware, a new beta service has been launched by Groundspeak called "Geocaching Live". Geocaching Live is a new "project focused on real-time social interactions among geocachers. While geocaching outdoors you can post logs, images and video related to your current geocaching adventure for others to see in real-time!".
While you can follow people's caching adventures in real-time from your desktop PC, it's really intended for use on mobile phones and PDA's. Unfortunately, my GPS-less mobile phone is not one of the supported models. If you look at the live map, you'll notice that the service seems to be more popular in Europe than in the U.S. at the moment. I have to admit that it is kind of fun to follow other cachers in real-time:
If you have one of the supported mobile devices, you may want to give it a try and see what you think of it. If you do, please post your experiences here, as I'm very curious to hear your reactions and see if this service will start to enjoy widespread use.
Thanks, and Cache On!
