Pinterest is making continued design moves and improvements. They’ve announced the launch of an updated “article” pin type that’s designed to expand Pinterest’s reach beyond photographs and linking to e-commerce sites. It turns Pinterest into an article-sharing service, with information like headlines, titles, and descriptions embedded into the pin itself. Today’s changes mean that extra metadata will appear automatically. It’s also introduced a “read it later” service in conjunction with the embeddable article pins, positioning the service as a potentially useful bookmarking tool for looks, websites, and interesting pieces; it could also provide incentives to advertisers who provide targeted offers. For instance, if a user has been pinning articles about running, a shoe brand might point the user to its athletic-themed pins, which also link to its e-commerce outlet. It’s a potent combination that might work wonders in the very near future.
