Not that I’ve extensive experiences with CMS but my reading and limited experience has turned me off of Blackboard for a number of reasons. In particular its lack of use of web 2.0 tools including RSS.

“…We have worked year after year with our clients to create powerful networked learning environments for instructors and learners at individual sites. Now, with the Blackboard Beyond Initiative, we are taking a critical next step by fostering a network of networked learning environments. The potential is tremendous, but it will take a lot of collaborative hard work to make the vision a reality.”
They aren’t there yet but this looks promising.
