I stumbled onto World Changing last week and quickly added it to the list. I think Dorsey's blog might have been the first step that led me to it. Anyway I remember talking to George Kelley a long time ago about an idea of a blog dedicated to workable outside the box Afrofuturist solutions to global problems in general, and black problems specifically.
I heard about The Index Awards through World Changing. Whether you are a diehard socialist or a hardcore capitalist, one has to be impressed with any effort to make automotive plants green.
