+      <a href="http://seatgeek.com">SeatGeek</a>'s stadium ticket maps were originally
+      developed with Prototype.js. Moving to Backbone.js and jQuery helped organize 
+      a lot of the UI code, and the increased structure has made adding features 
+      a lot easier. SeatGeek is also in the process of building a mobile 
+      interface that will be Backbone.js from top to bottom.
