Exactly, Udacity courses have around 50 minutes of lectures per week and 6 weeks of lectures. In total just 5 hours of lectures for the whole duration of the course. I don't believe anything substantial can be taught in such a short duration. On the other hand, most of MITx, and Coursera courses run for 10-14 weeks with 2-3hrs of lectures per week with additional assigned readings for some courses.

I personally had pretty bad experience with Udacity's AI-class last year, IMHO their teaching material is mediocre at best. I don't plan to waste any of my time on their classes specially when there are so many other better options available.

While I agree with everything you said, I kind of liked the AI-class because it was so short and superficial. I felt it gave me a very high level overview of field without taking up too much of my time.

So while the Coursera courses are better in the sense that they cover the material in much more detail and require that you understand the material much better to do the assignments, they end up being much harder for me to squeeze into my already hectic schedule. So in the end I think there is space for both approaches.

That is precisely why udacity courses are gaining popularity. They give you a false sense of accomplishment when actually the learning is very superficial.
Indeed, but there is nothing inherently wrong with superficial knowledge (as long you realize it is superficial). Before the AI-course I knew absolutely nothing about the field, now I know enough to start matching problem domains to techniques. Obviously I learnt nothing useful about how to actually implement those techniques, but at least I know what words to start googling for.

I disagree. Although I've only taken one so far (search engines), and I knew basic Python before taking the course. I like the small weekly practice sessions because they provide just enough breadth to prompt me to seek more depth, run pydoc, etc.

I find it more interesting to learn the standard library and take away a better understanding in this format, as opposed to reading a book or the documentation straight through.

I like the Udacity Robot AI course but I can see that it is dumed down. If the course wheren't I probebly would not have the time to talk it.

I trie do to Udacity Robot AI, Coursera Algo 1 and PGM. Lets see if I can handle that. My math background is much to thin and all the math stuff gives me a hard time.
