Now that the Computable Document Format (CDF) is officially released, the real fun has begun. At least for me. Whether or not you plan to start using CDF in your own work anytime soon, you've got to admit, it's pretty cool. From publishing textbooks and making complex information easy to understand to recreational games and everyday blogging, CDF truly makes it possible to communicate ideas in a more participatory way—as adopters of the format have already proven. It has been exciting to see the tremendous interest in CDF following last month's launch. Although CDF is a new advancement, it's clear that the possibilities it presents resonate with authors and readers alike, and hence with publishers as well.
