Airbnb was not just the website. The original network of hosts WERE airbnb people and friends. That is a huge asset for bootstrapping. And now they have real customer service- which I think is going to be the one thing (within their control) that is going to make them a success or not.

I agree a laundry startup should definitely be on top of quality control. Also, doing the laundry makes for a much better story. :> Imagine local news footage of thin dudes with sarcastic mustaches and tight jeans moving stuff from washer to dryer. That's gold.
