Here is the money quote for me:

"Were his readers not reading well enough, or did he not write it well enough? Disagreement is mostly blamed on miscommunication. The burden of clarity is now entirely on the author, which makes for dull and repetitive arguments  — and a demand that certain people come to represent, unambiguously, certain arguments. One’s cards must all be laid on the table, faceup, and one’s position must be unified. But the rise of misreading doesn’t give permission not to mean what you say."
