Word, Google Office and OpenOffice all come with a bewildering array of typesetting and automation settings that you can play with forever. Forget it. All that stuff is distraction, and the last thing you want is your tool second-guessing you, "correcting" your spelling, criticizing your sentence structure, and so on. The programmers who wrote your word processor type all day long, every day, and they have the power to buy or acquire any tool they can imagine for entering text into a computer. They don't write their software with Word. They use a text-editor, like vi, Emacs, TextPad, BBEdit, Gedit, or any of a host of editors. These are some of the most venerable, reliable, powerful tools in the history of software (since they're at the core of all other software) and they have almost no distracting features — but they do have powerful search-and-replace functions. Best of all, the humble .txt file can be read by practically every application on your computer, can be pasted directly into an email, and can't transmit a virus.
— Cory Doctorow on “Writing in an Age of Distraction”. I don't follow all the practices he suggests, but his advice is thoughtful and worthy of serious consideration by anyone who wants to write more and better.
