A few weeks ago, I wrote up some of the trends that I’m going to be watching in 2012. One was the interesting phenomena of access to assets replacing ownership of assets in more and more realms. Car-sharing services such as ZipCar, room-sharing services such as AirBnB, and project-based programming services from companies like odesk are upending a lot of our assumptions about what it takes to run a business. Indeed, owning anything may soon be seen as an industrial-age relic in a lot of cases.
