Questions, With No Real Answers

So what does it mean to "write it down"? To save a piece of information by putting it in a book, on a sticky note, or in a planner? To write/(take) notes instead of just listening? To send a handwritten letter or card, as opposed to a store-bought one, or even an email? How does the significance of writing versus memorization compare in our time? How would it have compared in the time periods we are discussing?

I really didn't do much research for this post, but I am enjoying the thought experiment.  "Critically" thinking about what we have learned about writing so far, and how it has changed our perspective on the world, and how it must have changed the ancients' perspectives.  So I am basically answering the previous questions with my personal, educated opinions, and I want this post to open the blog to yours too.
