AirBnb, etsy and Relay Rides are the current poster children of the sharing economy. If you don’t know what that is, it’s also called collaborative consumption or peer-to-peer selling. In other words, just fancy names for one person selling or renting their stuff to another person. Clearly this is not a new idea but it has never really been possible to do it on such a large scale. In the case of a site like Etsy – which describes itself as a global marketplace for unique goods, from furniture to food – they have allowed the local artisan to take his or her products far beyond the confines of their communities, towns, cities or countries and sell to a global market.
