I learned something cool this week. You can leave voice comments on a Google doc. This is very cool for teachers who want to leave a comment on a document for one of their students, but found that they had to write a lot. Now they can leave a voice comment. I am a writer and editor. So this could save me so much time when I edit, and this can save me if my editor uses this feature. Jennifer Roberts created this video tutorial on how to use it.
