Lecturers have as much right to deliver crappy courses on the Web as they do in the classroom.
Many people learn from these poorly designed classroom courses. Many can learn from poorly designed Web courses. Edward Bellamy was among those who pointed out that we always go into the future looking backwards. It is inevitable that our first forays into a new media will be done with the security blanket of traditional methodologies. I am not suggesting that we ignore good course design, but I would suggest that when teachers start adapting their lectures for the web, it starts them thinking about course design, for many for the first time.
