What a fantastic idea: Brian Chesky, co-founder of Airbnb decided that he will live the remainder of 2010 on Airbnb. He will stay 2-3 nights in homes and apartments on his website, across San Francisco. Originally he wanted to stay in every place available in SF on Airbnb. But, with 650 listings, that would take him a couple years. Still, by Christmas, he will likely break a record for living in the most homes in a single city. The benefit is clear; the best way to make a great product is to design something for yourself. By using Airbnb everyday, he will get to know the product and the people like never before.
So, he is either a homeless entrepreneur, or a guy with 650 homes in San Francisco. Depends on your perspective.
