Ok, I think the concept is interesting, the site is nice, and this could be popular in a down economy. However, here are my two concerns: a) Selling space in your house by the night this way most likely violates one or more state/local laws. First, you're probably not operating with a business license. Second, most cities have specific "bed taxes" (often 10% or more) for hotels. This is a significant source of revenue for touristy cities. Some cities also have specific laws about vacation rental properties (some actually don't allow rentals for less than 30 days)–even though I doubt these arrangements would qualify as a vaca rental. b) I'm no lawyer, but once you let someone pay you to stay at your house, it seems like you put yourself at a greater risk should someone get hurt or sick at your place. The last thing I want is some dude to pay me $50 to spend the night and then slip and fall in my shower ... I think couch surfing gets around this by acting more like a personals/ride-share/craigslist site that connects people. I'm not saying ABB will get in trouble–just that it may not catch on as quick.
