I just was quoted in a national article here in Canada (the Globe & Mail) that talked about using AirBNB... I've passed this story along to the author who is going to see about a followup.

This wont stop me from using AirBNB as a guest, but I was never comfortable with renting my own home anyway.

edit - if AirBNB kept a drivers license scan on file to confirm the credit card was the users, that would be helpful. I know that is difficult with privacy laws, etc, but when I check into a hotel I always have to show my ID to make sure it has my name on it....
