I have a love-hate relationship with footnotes. I like to use footnotes, because they allow me to remove stuff that isn’t directly relevant to the text I’m currently writing, while still keeping the information around in case anyone is interested. On the other hand, footnotes are a usability nightmare, yanking you out of your place in the text to a completely different place, and then back up. They are an interruption.
So I figured that it would be a good idea to show the content of a footnote as soon as you indicate that you are interested in the footnote. Namely, when you move the cursor over the footnote symbol.2 This allows footnotes to work on devices that don’t support mouse hovering, because you can still jump to a footnote via its link, but it removes the necessity of having to click on a footnote link for most people.
