Rachel Botsman is the co-author of a book with Roo Rogers called What’s Mine is Yours: The Rise of Collaborative Consumption (Harper Collins 2010). Is it about how virtual and real-world communities are coming together through organized sharing, swapping, bartering, trading, gifting and renting to get the same pleasures of ownership with reduced personal cost and burden, and lower environmental impact.
