The darndest things

People are doing such extraordinary things out there on the web!! Today I present interactive public projects. The goal of the degree confluence project is to visit each of the latitude and longitude integer degree intersections in the world, and to take pictures at each location. Another interaction site is PhotoTag.org, which tracks disposable cameras loosed into the "wild." And the ever popular WheresGeorge.com, which tracks U.S. currency by serial number. And last but not least is Bookcrossing.com where people share, track and review books let out into the “wild” for the largest book club/book exchange in the world.
