I agree completely on the Udacity model allowing you to work through at your own pace, as well as keeping the course open After it finishes. The strict scheduling thing with other sites drives me mad!

In addition to having a normal job, I'm a traditional university student, so any of the online classes I take are simply out of interest in the subject. I dip into the class when I have time, almost like a leisure activity. I just don't currently have the time to fit in more strict course work on top of my already over loaded class schedule and work week.
