Concrete Cartographer?

This morning's New York Times ran an interesting article on the rise of amateur map makers. The story has links to some interesting maps, such as the Top 10 Oregon Vineyards and Biodiesel Stations in New England. This article got me thinking about how a concrete contractor could take advantage of these online mapping tools. If you're a techy contractor, you could map out finished projects you've worked on in your community, adding photographs and descriptions of the job to each site. With the map posted on your website, potential clients could see images of your work and have the option of driving to the site to see the work up close.
