Via an Axis maps post about SXSW conference (would have loved to been there for that panel, sigh) I came across Stamen Design. Some very smart functionality wrapped up in great design.
An example is a map they built showing Hurricanes. Its interesting to compare with my comments on other hurricane map based projects that have been released. Other Stamen projects show us what the GeoWeb should look like, I just hope with the small amounts of time and money available to most of us we can begin to approach this level of design and user experience.
