Less "sticky" scrolling

This is a beautiful, succinct solution. I was wondering how to get the scroll to spin more freely, that is to go through more cards before stopping. I got the perfect answer here :

In brief, turn off the isPagingEnabled flag, and implement the delegate method scrollViewWillEndDragging. (The stackoverflow answer sets the scroll deceleration to fast, but it should be normal.)
