If a Stevedore Knew Petrarch. . . .

So I downloaded an app for my ipad; the NY Times crossword puzzle. I've solved two puzzles so far, needing help about four dozen times. It's amazing to me how many things I have no idea about--sports figures, rivers in Europe, battles that happened 500 years ago. And it's also amazing what you can learn about with Wikipedia in a matter of seconds. It is a little scary how much time I can spend on a puzzle, but then I rationalize that learning something new can't be all that bad.
