From MHS: "Beginning on 5 August 2009, we'll be posting JQA's line-a-day diary entries on Twitter, one per day exactly 200 years later....If you use Twitter too we hope you'll follow along and receive the daily updates. We'll be posting JQA's exact words (his entries really do work perfectly as 140-character tweets), and where possible we will augment the posts with maps showing his location (thank him for providing regular latitude and longitude readings), links to longer diary entries, and other information. His short entries are surprisingly rich, full of wonderful details about his reading, meals, weather, and shipboard activities."

Hat Tip to a faithful reader who chirped to me about this story.
