A really good take on all that BlackBoard is trying to do and how it still falls way short of a truly students centered software.
The End in Mind » Blackboard & the Innovator’s Dilemma
Blackboard remains first and foremost a semester-based, content-delivery oriented, course management system. The software is not (at least noticeably) evolving to become a student-centered learning management system. And while the addition of wikis and blogs inside the Blackboard system is as welcome improvement, there is still little or no integration between student learning tools “inside the moat” and outside of it “in the cloud.”It is for these reasons that I don’t count Sakai, Moodle, D2L or Angel amongst the biggest, long-term threats to Blackboard. Disruption will, I believe, come from another direction.
