This is another player in the game of rendering the page of the link that you’re about to click on before you click it. It’s like getting a decent performance boost for extremely little effort. is another one, and I’ve been sufficiently convinced by its methodology to the extent that I run it here on this site right now. I don’t really know the difference between the two. And they aren’t the only players either. Google has quicklink and there’s guess-js for really exotic preloading.

It’s a bit of a pity that Safari and Firefox don’t support <link rel="prerender">, as it really seems to me the absolute easiest way to pull this off would be to drop that on the page where, on mouseover of a link, it points to the href of that link.
