Our first tool out of the arc90 lab, Unobtrusive Sidenotes is a simple mix of Javascript and CSS that makes it ridiculously easy to incorporate sidenotes into your web pages or blogs. It even includes a handy set of colors (all set in CSS and tweak-able) to create that oh-so-subtle correlation between the sidenote and the relevant text."
