I disagree. I've been an Airbnb host for 6 months now ($13k+ of revenue so far for our spare bedroom / couch in prime SF location, fantastic reviews). We used to use the Craigslist posting feature in the early days, but we now get so many requests that we actually have to decline most, just from organic Airbnb search and referrals. The quality of users referred through Craigslist has historically been lower than organic Airbnb users, so stopping Craigslist was a no-brainer. In fact, the only bad experience we've ever had was a Craigslist guest.
