We are in the mdist of a re-architecture of the web, away from pages and destinations, towards completely personalized experiences built on an aggregation of many individual pieces of content. That's the case being made by a very thoughtful Web design/client communications firm in its blog. I'm not sure I agree that cards will revolutionize Web design, but I do think the "card" concept makes sense for communicating with clients and it's worth keeping an eye on.
"Content being broken down into individual components and re-aggregated is the result of the rise of mobile technologies, billions of screens of all shapes and sizes, and unprecedented access to data from all kinds of sources through APIs and SDKs," says the post by Intercom, a client communications and design firm. "This is driving the web away from many pages of content linked together, towards individual pieces of content aggregated together into one experience."
