I created a journal and found some neat features. First, it is set up like a normal notebook with lines and room for a title. While you write, Penzu keeps you informed on how many words you have written, when it was last saved, and the date you started the entry.
I can keep the journal completely private or create a public link. I created a public link which you can view here.
Penzu could be a fun way for teachers to get there students writing in a journal. There are fun ways to make it personal (like adding photos) and easy ways to share with friends. An example of a way to use it in the classroom is to have students write 10 journal entries over the course of a marking period. At the end of the marking period, students have to choose 2 entries to share with the teacher. Students could also collaborate with students from other classes who share similar interests, concerns, views, etc.
