I do sales for an apparel company called PACT. We make underwear / socks / t-shirts that are changing the world.... I encourage you to check it out.
The sales gig is the main reason I plan on using Airbnb, but may look into it next time I take non work-related trip also.
I love the idea of people being open to the idea of sharing their lives (homes) with guests and can't wait to meet and learn from them.
