Early last week I uploaded to my Academia.edu homepage a brief note signaling and explaining my decision to close my account on that site. As a medieval historian, I had been an active and enthusiastic member since 2010, with moderately high exposure, and while “On leaving Academia.edu” was meant as a provocative goodbye, I hadn’t expected it to draw much attention. In the four days that elapsed between uploading my note and closing my account, however, the text was accessed more than 22,000 times and the critical discussion board accompanying it (known as a Session) was still going strong, attracting some 2,000 active followers making numerous contributions, including from the site’s founder and CEO, its Product VP, and of course hundreds of engaged scholars and academics from around the world.
