John Resig: Secrets of the JavaScript Ninja Update
I've written a few short-ebook-like technical posts and it still surprises me the number of people who ask for when the PDF format is coming... I get that not everyone can have access to a web browser at every occasion they have for reading...but the web provides a much better canvas for illustrating technical concepts, especially with the ability to create interactive bits with JS. Save the couch reading for leisure/non-technical reading, and read technical pieces when you're on the computer (and have ready access to Google/StackOverflow).<p>On a selfish note, writing HTML seems to be much easier than producing a properly formatted PDF page. So I enjoy technical writing, but not enough to go through the hoops of for-paper (or paper like e-books) publishing.
