Tag and Scan
is another location based service, somewhat similar to Urban Tapestries
. With Tag and Scan, users can tag geographic places (in London) with pictures and text for other users to find when they do a scan of that area. The application can be downloaded and installed on any Java capable mobile, and users buy credits to spend on tagging and scanning. I'm really hot for this idea, and have been for awhile. To me it's a kind of digital graffiti that enables people to be even more informed while mobile -an evolutionary milestone I call Hi-Fidelity Nomad. Because we will depend on handheld devices to find this information, I sometimes call these devices Digital Divining Rods.
