Local Currencies - A Foot In The Door

Tim Harford considers the utility of local currencies such as Berkshares... I guess I basically agree with his conclusion that it's more style than substance, but style is still important! (Think of recycling - when you factor everything in, it's of pretty marginal benefit to the environment, but the "awareness footprint" is enormous - it gets people into the habit of incorporating sustainable behaviors into their daily lives and all that jazz.)
