The Fairfax Machine was built to be nothing if not efficient, so I won’t waste words with a windup: I start a new full-time job later this month. That will mean some changes here. I launched this newsletter in early June, a little over a month after I returned to The Washington Post as a freelance editor for its travel section. A simpler time, when I had more of it. In mid-July I took on another part-time job, editing Washington History magazine.
