"Collaborative Consumption describes the rapid explosion in traditional sharing, bartering, lending, trading, renting, gifting, and swapping redefined through technology and peer communities.
"From enormous marketplaces such as eBay and Craigslist, to emerging sectors such as social lending (Zopa) and car sharing (Zipcar), Collaborative Consumption is disrupting outdated modes of business and reinventing not just what we consume but how we consume. New marketplaces such as Swaptree, Zilok, Bartercard, AirBnb, and thredUP are enabling “peer-to-peer” to become the default way people exchange — whether it’s unused space, goods, skills, money, or services — and sites like these are appearing everyday, all over the world.
"As the Collaborative Consumption movement grows and evolves, so will this online hub. We believe in well-designed, simple tools that people can openly share and build on. Over the next few months we will provide you with resources, stories, info-graphics, and tools to fuel the development of Collaborative Consumption and create the forums for you to discuss and spread your ideas...."
