A lede, rhymes with “seed,” is the introductory sentence or paragraph in a story. It is an intentional mispelling, harkening back to the days when newspapers were using printing presses made of lead (rhymes with “dead”). We don’t actually use printing presses anymore, although sometimes it feels like it.
The New York Times has a great blog of a similar title, The Lede, but they talk a lot less about running than I do. I also talk a lot less about Barack Obama than they do, but I do think about him a great deal.
