The only infinite scroll I'm kinda OK with is DuckDuckGo. When it comes to news sites with infinite scroll, I almost never want to continue scrolling past the original article.

What I'd like to see go more than infinite scroll is sticky headers. It's one thing if your site is effectively an app, but if a site is supposed to be mostly prose then I don't want your stupid useless header in the way of screen real estate. Worse yet, you make the problem worse by having the header pop out and retract if I scroll 1px in either direction. ANNOYING.
