Our school uses the Blackboard CE Learning Management System, and my online philosophy courses are heavily dependent on threaded discussions.
Rather than stare at a computer screen all day, I've taken to compiling all the discussion comments, pasting them into a Word document, then sending the document to my Kindle. In a few seconds I have the complete discussion, and I can add notes and grades from my easy chair. The e-Ink screen is easy on the eyes, too.
