It's a really good overview based on his own experience of participating in one.
What jumped out at me towards the end of the post was this:
Education is primarily driven by motivation, and online learning doesn't do anything to address people's motivational needs. In fact, the nature of online education strips away many of the components that keep students engaged and committed.
Many of the factors that online education advocates claim are a benefit, such as time flexibility and the lack of classrooms, are actually a hindrance to learning.
Studies have shown that a fixed structure and the sense of belonging that comes from a student body improve completion rates.
Allowing students to study on their own removes these components of the support system resulting in lower rates of course completion.
Like Steve, I am not so sure I totally agree but it does remind me of this quotation from Plutarch:
The mind is not a vessel to be filled but a fire to be kindled.
Seems to me, this is the key point that is missed in education time and time again.
