Is this comment satire?

>> I can feel the morning coffee and feigned interest

PG admits he rereads some of his sentences up to 100 times in his revision process in the very piece you criticize.

>>The author could put down his morning coffee and instead describe part of the story to his wife or secretary and see the reaction of someone outside the field responding to what could be an interesting topic.

His writing also addresses this in the same writing, advising people to specialize with a target audience... Did you read this piece?

This is either funny trolling (giving condescending essay advice to one of the most succesful essayists of our era, on the platform he created), or woefully lazy.
