How To Start a PSS, a Product "Service" or "Sharing" System, Part 1

An ongoing series about how to design a system to share goods that you probably shouldn't be buying -- clothes swaps, DVD and game rentals, freecycling and other networks. The more people share, the less they buy, so these systems let you reduce energy consumption and cut back on landfill use. Big self-promotion disclaimer -- I'm the author of this series!
