"At teachingopensource.org, we think so, and we wrote a book to help.  The following excerpt comes from the Foreword of our new textbook, Practical Open Source Software Exploration, which is licensed under Creative Commons BY-SA-3.0.  It’s a book that works like an open source software project.  In other words: patches welcome."
