Really writ­ing forces us to lock the words into what­ever con­trap­tion is being used to write. I like type­writ­ers because it’s hard to take out the paper and crum­ple it up while writ­ing. The eas­i­est move­ment is FORWARD. Typewriters are momen­tum machines. Real writ­ing pushes for­ward. Tweets push in every direc­tion at once. These are not value judge­ments, these are just some observations.
