However, it’s also true (according to the eLearning Guild’s annual reports, anyway) that most of the elearning development world uses rapid development tools, and those don’t have all the capabilities of Flash either. So my open question to developers and designers is:
What do you need for your course development that HTML5 doesn’t provide?
Or, alternately, What do you need for your course development that you’re not sure HTML5 provides? If you ask a question along those lines, I will do my best to answer it here.
