Paul Adams – Why cards are the future of the Web:

“In addition to their reputable past as an information medium, the most important thing about cards is that they are almost infinitely manipulatable. See the simple example above from Samuel Couto Think about cards in the physical world. They can be turned over to reveal more, folded for a summary and expanded for more details, stacked to save space, sorted, grouped, and spread out to survey more than one.

When designing for screens, we can take advantage of all these things. In addition, we can take advantage of animation and movement. We can hint at what is on the reverse, or that the card can be folded out. We can embed multimedia content, photos, videos, music. There are so many new things to invent here.”
