The first sentence can make or break a book. Perhaps we exaggerate, but only in the hopes of capturing your attention. Yet, it's true that the first lines of great books stick in our heads for the ages: "Call me Ishmael." Painful openings usually mean we won't make it to the last page: "It was a dark and stormy night." Twitterlit capitalizes on the magic of these "literary teasers" by harnessing Twitter, the latest darling of Web 2.0 technology. For either logophiles or aspiring writers, Twitterlit's twice daily delivery of first sentences may be the most condensed form of education and enlightenment you can get.
