I agree with the cautions on trusting an instructor, yet at the same time a student is not a good judge either. If I am learning something for the first time, how am I to know that what I've been taught is good until I have a chance to put it to use?
This is why most universities have an accrediting body. That body audits the school to be sure they are offering a sensible curriculum, and that the faculty are qualified to teach the material. I think it is safe to assume that some of these online schools will eventually submit for some form of accreditation (if they haven't already). That process will flesh out the kinds of problems identified in this particular online class.
So you think that money is the root of all evil. Have you ever asked what is the root of money? -- Ayn Rand
