Speaking of 18th- and 19th-century diaries, I have been following John Quincy Adams' twitter feed for over a year now.  The Massachusetts Historical Society posts his short daily diary entries every morning, 200 years to the day that Adams penned them.  Short, quick, to the point.  Today's tweet from Russia: "4/14/1810: Met and walked an hour with Pardo. Emperor passed us in a Sleigh. Evening at de Bray's. Chess with Maclure 1:30."
