It was my impression too that the photo could be appropriate. EDIT: I've edited my comment to make it more constructive. Brian, I think you are doing a great job with AirBNB and handling this situation. Please take these comments as constructive criticism regarding the photo (in this particular situation).

For PR reasons you need to smile, even as JimmyL critiques the sincerity of your orthodontics. Smile on the outside and ask them in a chipper tone how you can be of service, but in the end, seriously, f* em. There's an insane amount of implementation work to do to get this 24/7 support and insurance program operational. F* em all and just plow. Pot of gold at the end of the rainbow. And your real customers and fans will thank you for it.
