This is the key. You're valuing your time at nothing. Which is fine, if it works for you.
It doesn't work for me. I want to do a quick search, using the basic parameters, and to be able to trust my search without going full CSI.
Increasingly, with Airbnb (also booking.com, also eBay, and now even Amazon), the results of a quick search cannot be trusted. In the case of Airbnb, hotels offer a "more reliable" alternative for the busy person.
