Our friends at WorldChanging have worked very hard in the past year to create WorldChanging: A User's Guide to the 21st Century, and today is the big day. If you want to help the WorldChanging community hack the publishing system, please consider buying your copy today at 11:11 AM Pacific Time (2:11 PM Eastern Time). Also, don't forget the book tour (schedule here): Last night at the launch in Seattle, more than 300 people showed up and Alex Steffen and Bruce Sterling spent more than an hour in conversation with the crowd (apparently Bruce was throwing chocolate Earth balls in the audience). As for the book itself, it's beautiful, it's heavy (literally, and with content) and it's potentially quite world-changing. For those who are wondering, the book is made with chlorine-free, 100% post-consumer recycled paper and wind-power credits were purchased for the equivalent of electricity it took to make it. You know what to put under the xmas tree this year (or whatever occasion you have to give books). Stay tuned to TreeHugger for a full review in the coming days. More pictures below.
