I expect tagging and social bookmark technology to make incremental gains within enterprise environments over the next few years. I don't expect the type of proliferation that wikis and other socially-oriented tools have experienced but when applied effectively, I think the impact will be just as powerful. What makes this implementation interesting is the integration with LMS systems. It's not the LMS integration per se that I am intrigued by but rather the notion that participation in a particular context (in this case, a course association), causes an application to generate certain tags. This doesn't replace the ability for users to to apply any tags they come up with, for whatever reason, but it does aid in discovery efforts which provides for a non-intrusive mechanism for individuals to "find other people like me" around a formal institution (the class, the course). We see this now when events are held are organizers request that people blogging or sharing photographs assign a special tag.
What makes Scholar different from other social bookmarking services you may have used or heard of (e.g. del.icio.us) is how it works in an education setting. Scholar has all the typical features you'd expect from a social bookmarking service (tagging, tag clouds, RSS feeds, a bookmarklet for browser integration, etc.), but we wanted to make social bookmarking more relevant for Blackboard-powered courses and academic research. We spent a lot of time thinking about the problems students and faculty encounter when they go about doing web research or building engaging courses, and getting feedback on those ideas about how social bookmarking could be enhanced for education. I'll give you a couple examples.
Pretty much all students and instructors do web research as part of their academic work. When they find resources that they want to keep around, tagging them makes them easier to find later. Since they're students and teachers, we know that it's likely that they are saving the resources for a particular course, or for research in their discipline, specialty or major. So we created special tags that let users tag for disciplines or specific courses really easily. We make it extra easy by using the integration with the Learning System to automatically generate your course tags based on your courses enrollments in Blackboard. You won't see any course tags when you browse the public site because we're protecting student privacy by not disclosing users' course enrollments.
