Slate on Building Crossword Puzzles

Slate features an interesting article about a face-off between human-built and computer-designed crossword puzzles. Coincidentally, the National Puzzlers League meets in San Antonio this week for their annual convention. Many of the folks mentioned in the article will be there, but I have to miss it. The NPL con happens too close to International Puzzle Party, and I have to choose. This year, I'm going to IPP.
