What is a Card?
Khoi Vihn, “What is a Card?” 2014
We used to sit down with software and point and click on things; now we carry software around and tap, swipe, pinch and zoom on things. As our computing habits have gotten more mobile and more physical, the metaphor of pages, which implies a more focused, dedicated frame of mind, has become less useful.
Cards offer an alternative metaphor that’s much more complementary to how we use phones and tablets.
