This is a great point. The model probably could have worked, it's just that the framework isn't very desirable. A really easy to point at example of why this is so hard to do: they implemented their own formula for inertial scrolling, since mobile browsers don't really (or didn't at the time) let you interact with scrolling behavior at all in javascript. So simply scrolling through a site written in famo.us felt _off_. It's a small thing, but emblematic of the problems with their approach, in my mind.
