The first time I taught a college course called “The London Diary” for young Americans studying abroad back in 2002, each student ended up with a tangible book of memories, a handwritten record of their semester in London. But when I taught the course 15 years later, the first question my students asked was whether they could keep their journals online. The question brought home to me how the image of a diary has shifted from words scribbled in a blank book to images and digital text on a screen.
