Prefetch UI content ahead of scroll

The UI is impressive and snappy and I think some pre-fetch of content off the view wouldn't slow down the initial page load. It would make the UI feel more snappy.

There also seems to be a bit of a delay in the actual request for the next row of content. The network request doesn't go out until react has finished its transition/animation. It would be great to have the request go out before the animation is started.
