Pinterest is a virtual pinboard - a place where you can create collections of things you love and “follow” collections created by people with great taste. People use Pinterest to collect and share all sorts of things. It is a powerful new marketing engine and what I mean by a “marketing engine” is basically that with a single picture or video, you can reach millions of people if your “pinned” content goes viral.
