It would be neat if caniuse had a widget that you could embed which would show % usage at time of reading the post, so I could know right away instead of looking each feature up.

You'd also have the advantage of the article always being relevant.

It does: just add "/embed" to the URL. E.g. http://caniuse.com/datalist/embed

Exactly what I wanted to ask. Link prefetching seems super useful.

Scroll down for list of browsers (and versions) that support prefetch / prerender / and other hints.
