If you are a Blackboard user, here is a del.icio.us/Scuttle social bookmarking service that plugs right into the learning management system. It’s called Scholar. You must have Blackboard to add bookmarks to the system. Without a Blackboard server you can search through the links made public by Blackboard users. Browsing isn’t too bad because all the links are connected to courses with academic content. There aren’t as many links in the database, but a search will have a higher probability of a valuable hit.
Having social bookmarking built into the LMS solves a lot of the problems inherent in larger sites like del.icio.us. All the bookmarks in Scholar can be grouped by course. A student or an instructor can have generic bookmarks or bookmarks associated with specific courses.
Now we need someone to integrate Scuttle into Moodle.
