I love this YouTube video by Campbell Mithun to help explain what the sharing economy is.

Airbnb is one of the hottest website / apps that makes great use of the up and coming sharing economy. A few weeks ago I went on a trip to San Francisco and used airbnb to help me find a place to stay. I absolutely loved it! Airbnb gave me many options of places to stay that were within my budget. I highly recommend trying it out on your next vacation!
