Citysearch: Mobile Users More Likely to Write Reviews

I spoke to Citysearch CEO Jay Herratti yesterday about the Citysearch redesign and the mobile app. Among other things he expressed surprise about the volume and quality of reviews coming from the company's mobile app. The verbatim quote is “I’m blown away with the number of reviews" coming from mobile. 

The company also told me that "a user who comes to from a mobile device is 5x more likely to write a review than a user who comes to through the website."
