Not defending or opposing the thesis of the essay, but this person's blog has (roughly) one post every day... it makes one wonder how much thought and editing goes into writing at that pace.

Most serious writing I've seen is released at a slower cadence. A large volume of content makes me equate its source with the 24/7 news cycle -- more is better, keep pressing the viewer/reader's buttons (outrage, moral indignation, etc.) to keep 'em coming back.
