This blog post is a short meditation on the writing systems of journalists. One (aged 77) first takes notes on "laundry board" & then transfers to a typewriter & then to a computer. Clive Thompson points out that taking notes in longhand forces him to make choices *as* he writes, while taking notes on a computer allows him to note everything, and then make those kinds of filtering choices later.
