Swiping between cards - metaphor end-of-the-road?

[Matt Maier]

That's a good point. Android apps commonly uses "swipe down" to trigger a
refresh. The swipe still physically happens, but there's just a gray
background behind it, and it pops back into place and resets.

The main problem seems to be what happens during a swipe. Part of the
effect is the feedback of seeing one card move on top of another. After the
swipe is completed we can just use regular messages to do whatever.

Another swipe effect would be pulling the next card in to fill the space
left by the moving card, rather than the next card being stationary
underneath.
