Appears to be Ruby on Rails (looking at their job postings: http://www.airbnb.com/jobs)

I'm curious as to why you care.

In theory, and practice, you can build a site in anything with enough effort. Scheme, Scala, Go, Haskell, Clojure, etc. However, it's good to know that other big sites are using your preferred choice. A lot of usage usually indicates mature frameworks, larger user community, ability to Google common issues, find developers as you grow, etc.

What was that YC site that initially used Lisp but switched to Python at the end because they couldn't get something to work?

Looking to build a site with similar functionality and with little coding experience thought it would be helpful to know.
