Blackboard 2.0 is a proposed service that aims to streamline course delivery and access to information for students. It utilizes four main services - cloud computing, web content management, social networking, and predictive analytics. The services allow course materials to be accessible anytime from anywhere, simplify course building for instructors, and streamline information for students. Potential advantages include simplified data entry and more informed decisions through predictive analytics. However, challenges include full integration into current university systems and privacy issues connecting to some student services.
