The sharing economy is the future. Airbnb, Couchsurfing, Cookening are all projects which let you share services via the internet. It allows people to support your their community, save money, and meet new people.
Snappcar is a new example I heard about yesterday. People put their cars up for hire and people who need to use a car locally can log in to Snappcar and borrow them.
This is one that I may actually use once I have my drivers license. The thing about this sharing your house or food is that it gets fairly private. A car may be for some, but I don’t see it that way. A car is a polluting thing so we may as well be sharing the ones that are all ready on the roads in stead of all getting our own one.
