Gather round, children, while I tell you of the days when editors changing stories used to take a pair of scissors and cut a paragraph or a sentence. Then they’d get out a gluepot (look it up) and swab the back of this tiny curling piece of paper, getting goo on their fingers, and paste it onto the story where it made more sense. In the 1970s a computer scientist named Larry Tesler invented the software that lets you move words without scissors or goo. Count yourselves lucky, children, except for the fact there were a lot more jobs editing stories in the olden days.
