19.20.21
Derek Wenmoth from Core, just blogged about this.
19.20.21 is a investigation into 19 cities, each with over 20 million people, in the 21st Century, hence the name. The projects purpose is to look at business and urban growth in these cities over a 5 year period and publish this information via a variety of channels or modes (web, books etc).
This is a site that geographers (and many many others) the world over will be flocking to in droves.
