• Plan for discomfort when traditional roles and structures of classroom authority are disrupted
• What does this mean?

Yes, but there is also the danger of encountering nonsense (which many people are attracted to) and offensive material very easily.

One has to be careful that there use of Twitter is not another excuse to see one's education as a form of entertainment. 

Where is the sustained inquiry when reading people's brief explanations on a twitter page? There isn't any.

I disagree. Students may be paying tuition, but they should not be seen as consumers. This is the business model (vocabulary) imposed on the academy.

When I teach I do not see myself as a salesman of knowledge, and the institution I work in is not a corporation or a business. 

Students are consumers of information, but not market consumers. To commodify knowledge is to turn the classroom into a shopping center...which it isn't.

"Just as in construction, poorly built learning scaffolds can sabotage future learning." Sabotage is the wrong word here. You mean undermine the foundation to learning.

The Scaffold metaphor works, but it is still insufficient. This is otherwise known as foundationalism. However, it is hardly comprehenesive of the full measure of the way students can learn.

What about the role of imagination and interdisciplinary learning? Where does this fit into the metaphor?

See coherentism. Some students learn discursively...like contemplating stars in the sky or a "web of possibilities." Not all learning needs to be predictable or lock-step. This is far too… >>>

"Remember, what you won't tolerate in your F2F course, you should never tolerate in your online course."
 

This should read "wouldn't" not won't. Also, students using an Alias? What's preventing friends of students from completing assignments?
