I didn't write this consistently; the time was broken up over a coupla days. I would say an hour with a lot of backtracking and pausing to think of funnier things to insert.
On average, a good post takes about an hour between writing and proofchecking. Shorter ones (one screen full, which is the traditional measurement) should only take about a half hour. Reply
