Dear Airbnb team and design crew, you did a great job! The landing page is great and I´ve always been waiting for the infinite scroll solution for your service you implemented right now. Especially I really like the Picks and Collections which have their own style and a cool font. Is your designer featured on dribbble? For sure, these images are becoming the "Google Doodles" of airbnb.
I think the whole website looks nice & furnished right now and underlines the community culture. Maybe you can still tune the city listings page a little? They grey containers right here http://www.airbnb.com/s/San-Francisco--CA could be improved.
@airbnb: do you plan to offer the "Wish List" in combination with a gifting function, so that a user can gift his girlfriend or whomever with X nights in Wish List place younameit? I think if you integrate that into Facebook "X just gifted Y with Z nights in this beautiful room (link) in City Awesome", it would be nice.
