Alex from Worldchanging sez, "It's our sixth anniversary today, so we're running the 70 of our most popular and enduring pieces, in the 7 categories – Cities, Shelter, Business, Politics, Planet, Community, Stuff – we cover. Some great stuff here, which leads on to other great stuff, over 10,500 pieces in all… if you want a quick reminder of the ideas Worldchanging's been exploring these last six years, you couldn't do better than this. It's sort of like How to Change the World, an Overview"
