Yes, it was quite nice the first time I scrolled down, then became somewhat distracting. The fade in happens after you scroll past the relevant heading for me (Firefox, Ubuntu 12.04, 1080p screen). https://dl.dropbox.com/u/8403291/stevelosh.png https://dl.dropbox.com/u/8403291/stevelosh.png and https://dl.dropbox.com/u/8403291/stevelosh2.png https://dl.dropbox.com/u/8403291/stevelosh2.png show what I mean. I actually do like the marginalia, like in Tufte's books, side boxes as a sort of commentary or summary of the main text. I'd prefer them to always be there. Lets face it, on a widescreen monitor of modest resolution, the page looks thin otherwise.
