I took ai-class as well and was actually really disappointed in Norvig's teaching style (considering I generally love what he writes). I thought Thrun on the other hand was great, so I have a lot of hope for the udacity courses. My suspicion is that each instructor had different levels of commitment to the project, and since both are extremely busy this affected the presentation. My biggest issue with ai-class was that in almost all the exams and homework there were quite a few very poorly phrased questions. In a human-graded exam/hw this isn't so bad since the ability to "show your work" usually allows you to misunderstand a question and demonstrate that you do understand the material. In general I though very little effort was put into creating assignments that worked well for an online environment (ml-class did this perfectly).
