Wallace on Punctuation

One measure of how good the writing is is how little effort it requires for the reader to track what's going on. For example, I am not an absolute believer in standard punctuation at all times, but one thing that's often a big shock to my students is that punctuation isn't merely a matter of pacing or how you would read something out loud. These marks are, in fact, cues to the reader for how very quickly to organize the various phrases and clauses of the sentence so the sentence as a whole makes sense.
