If you don’t know, Moodle and Blackboard are two of the many course management systems/“virtual learning environments” for posting class information online. One of the mysteries of the software industry is that Blackboard is still in business. Blackboard was buggy and had a poor user interface ten years ago, and hasn’t really improved since then. I have tried to get rid of it since I was first paid to help set it up. Plus it is expensive. As in hiring someone to customize and run one of the alternatives is less expensive. Moodle, on the other hand, is cleaner, faster, and open source.
