Lisa Sjogren's presentation introduced the social bookmarking tool Diigo. It covered how Diigo allows users to bookmark and annotate webpages, share bookmarks in groups, and embed bookmarks and tags on websites. The objectives were to remember, mark, and share websites using Diigo, explore its tools, join a collaborative group, and build individual Diigo accounts. Ways to use Diigo in classrooms included generating website lists for students, keeping resources online for access anywhere, and creating student accounts for controlled research groups.
