I think the term 'Sharing economy' is still a new term for most as its hard to understand that renting something is basically sharing.  I've asked a few people and although they have used for e.g. Uber and Airbnb.. they knew nothing about the sharing economy and that uber and airbnb is basically a sharing service.   I think over time as the project grows this concept of sharing will become more mainstream and understandable for most.
