Hi Whit!
Airbnb has most certainly monkeyed with the search results. My place (in Crozet, btw, Hi neighbor!) is only visible for the last week and a half, if I lower the high end of the price range, or filter for Pet Friendly. So my listing is invisible to people who don't travel with pets (most people) or to travelers who don't think of reducing the price range filter.
I contacted Airbnb via twitter on 11/29 and got a call and an email - but no solution. Just a "thank you and we're looking in to it" kind of response.
Your Airstream property looks pretty cool!
