Funny, as I have found most of the newer courses seriously lacking any tangible depth or usefulness (Intro to Hadoop/MapReduce took a few hours and barely covered the basics). The old Artificial Intelligence or Parallel Programming are probably some of the best on the site.
That's my general impression as well. That's why I didn't get a master in CS rather a MBA which is kind of relaxing and fun (my company offered for my master degree, otherwise I'd never go... ). Pretty much all CS master courses not that much in depth in comparison to an engineering master degree. And all these tech degree are quite "generic", which greatly reduce their usefulness in real life.
I feel like graduate school are for people who do not know what they want or interested in at the moment. Once they do, you already locked up in that degree plan, and have no time to go ahead implement the idea.
I much prefer to take classes from edX-like course education sites which I'm not obligated to anything. Once I feel I got a hang of this new field, I can just go and do my stuff.
