Abstract from the website
"An emerging class of online tools, including Pinterest, Scoop.it, EduClipper, and others, allows users to quickly and easily gather, organize, and share collections of online resources, particularly visual content. These applications make it easy to collect and post disparate bits of content, providing visual groupings at a glance that can reveal important patterns. In academic settings, they can facilitate more visual thinking and discussion among students while providing a means to share collections of online content."
