I found this short video from Social Media expert Chris Brogan. Chris was giving a keynote speech at the Web 2.0 Expo with using a case study of the Roger Smith Hotel.
It is well worth the ten minutes as he gives a case study on why the Roger Smith Hotel is outperforming The Four Seasons Hotel in Manhattan. (Can't see it? Click here)
This is the link Chris mentions listing other case studies - http://delicious.com/chrisbrogan/casestudy/
You can find more information about Chris's experience with the hotel, and even a video he shot from his bedroom here.
