I took the AI Class, and I have just finished first unit of Udacity's CS373. So far I'm impressed; they seem to have taken the lessons learnt from AI Class on board and made a very usable system. The presentation of the content has been much improved. The "whiteboard" is now electronic, and it is still visible though the person's hand. Furthermore, I haven't noticed any errors yet - they seem to be much better at avoiding them. The biggest improvement is that some of the quizzes now involve programming some of the concepts in Python, which IMO works really well as a teaching tool. There is still a slight problem that people are starting at different levels, so some fairly basic concepts need to be revisited, but I imagine that will improve as Udacity offer a bigger range of courses.
