It is an advanced social bookmarking site -- bookmark pages, highlight, add sticky notes, create lists of specific bookmarks, or create a group to work with others on a project. Like most social networking sites, you can friend people and see what bookmarks/groups you have in common. The site connects you to other users with similar annotations -- "you are what you annotate."
