Similar in effect, but not in method. Turbolinks fetches pages after a click like normal, but swaps the body tag from the new page into the current page, cutting local render times.
Interesting. So this could be used internally in a web app i guess.
Would it make sense to combine them? Instant turbo links.
Yes, it would make lots of sense. If Turbolinks adds a 'prefetch' mechanism, it will get even faster.
