My biggest single problem with Facebook Paper is that the UI has too many possible interactions, making it confusing to decide how to navigate. There's no mindless default.

With the Facebook app I scroll down. With Flipboard I flip. With Facebook Paper I... swipe up and down and left and right and pinch and tilt. Fancy but unusable.

Facebook Paper was codenamed "Konami" during development because the navigation pattern is "Up Up Down Down Left Right Left Right..."
