Blackboard is a badly-bloated course management tool that is mostly convenient for students, and mostly inconvenient for faculty. Periodically I point out problems with the tool. My most recent peeve is that posting an announcement, the instructor always must check a box saying that the announcement is available over the length of the course, rather than just temporarily. This is a failure on the part of a Blackboard "designer" to understand the basic principle. keep the common case fast. Par for the course.
A more amusing bug that I've noticed today is that if an instructor posts an HTML document that includes a commented-out link to an image, Blackboard prompts to upload the image. Dumb. Why interrogate the user about HTML source from a tool that is clearly incapable of parsing HTML source?
