You miss the point. AirBnB redesigned how one acquires temporary housing when visiting another city (staying at an individual's house, arranged via an online marketplace). Their site's visual design is really ancillary to that.

I don't think AirBnB has really added that much to the VRBO experience or business model.

They did something that caused them to stand out and become wildly successful. If that something is caused by the site being more usable or somehow easier, then they have added something to the business model.
