Hats off to Yahoo! for creating this style guide for the Web. While the AP Stylebook has served me well over the years, this online guide for the digital age has a lot to offer. It features articles on how to write for the Web, search engine optimization, and eye tracking. It even lets you download its word list to use as a starting point in creating your own.
You can win a copy by answering the question, What have you learned from the guide that you did not know before? Contest ends today.
