I don’t know people who read at work for fun. They read because they need help doing their jobs. That means they’re looking for documents they can USE.
Few things make a document more usable than format. (I’m talking about white space, typography, etc.) Revising Professional Writing devotes a chapter to this topic. I’ve been using short video tutorials (<15 minutes each) with my own professional writing students for years. It means I don’t have to spend class time giving these tutorials. Plus students can listen to whichever tutorial they want whenever they want.
Anyway . . . I’m updating those old videos and posting them here. I’ve been using technology long enough to anticipate problems so . . . let me know what you think.
