Clearly this is a mobile only library currently. It looks really nice and there's nothing wrong with having a mobile only site/js library/tool. However I'm currently consuming morning news and media at my PC and don't want to get out a tablet to check this out so I will never really know how good it might have been on mobile.

Desktop-only interactions on mobile just makes a site seem simple. Touch=click, swipe=scroll. As long as buttons are big enough and have enough padding no one complains and they use it fine.

Mobile-only interactions on desktop though are generally horrible.
