Whereas the professor is obligated to read through ten pages of whatever crap I scrambled together three hours before the deadline, you, the reader, do not share that same obligation. If whatever I’m writing has moved through my bowels twice, the reader can just move on and carry about her business.
So while I don’t get graded on this, it does mean I need to be more vigilant about what I post — first, so I don’t waste the reader’s time, second, so I don’t feel guilty about wasting the reader’s time, and third, so I can enjoy the satisfaction of a job well done (however I choose to define that).
