Well, OK. Personally, I moved away from using hover for anything important on my sites, because it has such a restricted application. It either doesn’t work or works unpredictably on phones and other touchscreen devices, and is pretty useless for people, like me, who use keyboard navigation. But now I read academic papers using the sioyek PDF reader, which makes such good use of hover that I’m regaining some affection for it. (Hover over a reference to a figure to see the figure pop up without losing your place, for example.)
