One of the things I've always found a bit odd about Coursera is the lack of general subject forums. Sure, you can meet with and interact with some students in the forum of a particular course, but then when that course is over the forum empties out. And if you are taking the course on your own schedule, the place is often empty because you're doing a lot of the work after the course ended. I understand that open ended courses might not have the volume to create an active forum, but why not create subject forums where people can discuss things and create a community? In my experience, communities are a very important way to give people the motivation to complete some of these courses.
