In hindsight I think you need these basic ingredients in order to engender a successful connected learning MOOC:
If you still want to make your own MOOC after that, start with people of good will. Figure out who you are together. Decide what is important. Set a schedule. Create workflow and routine to create together. Move slowly, but don’t stop. Eventually, what will emerge is a governing aesthetic that includes the good folk, the good values and the good spaces you feel that you need to succeed with your own MOOC project. You will then have your own orchestra, your own players, and your own music that fits. Not someone else’s.
