I hate infinite scrolling with a burning passion. You're reading the article and scroll down 2 pixels too far and WOP you're loading something again. Qz.com is one of the worst offenders here.
In this case I called it pre-loading (it's not infinite either). You get to the end of an article and we have the next one ready for you. No need to make a choice on what to do next, just follow through if Headline is of interest.
Not perfect, but those who use it most do love it.
