From a Hypothesis Announcement:
Less than six months after recording three million annotations in April, and just over a year and a half from our one millionth annotation, we are proud to announce four million annotations, led by strong engagement from students and teachers in another record-breaking fall academic term.
While open annotation across the broad community supported by Hypothesis goes beyond teaching and learning to include areas like scholarly publishing, research in the sciences and humanities, and journalism and fact-checking, we continue to see usage patterns clearly tied to course-based use in academic terms. Fall 2018 is the fifth term in a row where we’ve seen substantial growth over the same semester a year earlier.
