On the shameless self-promotion front, I want to mention that we're co-hosting a book launch and networking event with Worldchanging here at WRI on Friday.? Full details of the event are on the World Resources Institute web site; the basic gist is that we'll have presentations from WRI and Worldchanging staff, including one from Worldchanging co-founder Alex Steffen that's gotten good reviews elsewhere on their book tour.

NextBillion readers may or may not know that I also spend some time writing for Worldchanging, and that Al Hammond has been featured over there as well.? Our new book is a 608-page compendium of tools and ideas to change the world; one reviewer described it as "the Whole Earth Catalog for the digital generation."? Come by to meet the people behind the scenes at NextBillion.net and Worldchanging.com; we'll have plenty of beverages and an open space to facilitate networking.
