I like Airbnb, because it's made staying abroad much cheaper and nicer. I also like being able to rent a taxi on an app in a new town.

I think it will be like Amazons coming doom, death by a thousand cuts. You can have this horrible model that can't handle edge cases and until you burn too many people, it seems to work. But once you have sold fakes, or ruined (or added thousands in expense) vacations to enough people I know, your business is dead to me.
