Throughout the ages of educational ideas and philosophies teachers have been big fans of having their students keep a journal. Journals are kept in language arts, foreign language classes, and I have seen them in science classes. Students don't particularly like doing them unless they enjoy writing. If given a choice between keeping a journal in their spiral notebook and keeping it online, I would wager that a majority of students in this digital age will prefer to keep it online. So why not give them the choice and tool of Penzu.
