So I recently gave a class at Princeton Public Library on Google Drive. I speak about it frequently to organizations and internal groups as well. It is a topic that is nearly as close to my heart as visual literacy, and one that strongly affects the way I learn, work, and live. The accompanying presentation is at this link on Google Drive. And that, in effect, is part of the power of it. I can control who gets what kind of access to all of my documents going back to my first digital document, and can grant access or editing rights with a link.
