TileMill: a New Open Source Web Map Design Tool

On the OSGeo mailing list was mentioned TileMill, a new open source Web map design tool.

From the post: "TileMill is a tool for cartographers to quickly and easily design maps for the web using custom data. It is built on the powerful open-source map rendering library Mapnik – the same software OpenStreetMap and MapQuest use to make some of their maps. TileMill is not intended to be a general-purpose cartography tool, but rather focuses on streamlining and simplifying a narrow set of use cases. And how government agencies can use it."
