In Dennis Crouch's "Patently O" blog, I came across another interesting map that marries legal content (in this case, openings for patent jobs) with Google maps. It's the Google Patent Map.
A job search is a natural fit with a large-scale map. Most people are going to be quite limited in where they could possibly be interested in working, yet, some people, particularly in hard times or at the start of a career, are quite flexible. A zoomable map like this accomodates both types of job seekers. The flags here provide fairly minimal information about the opening, but do provide a link to fuller information.
