Same.

I've seen a bunch of Quartz articles coming up in the variety of aggregators I use. Unfortunately, they don't load.

Pro-tip: You're trying to get me to spend time reading your content. If I have to mess with my browsing setup to do so, I'm going to skip your articles. And I do.

I had the same result with chrome. Ghostery was the cause, but like another comment pointed out just delete the overlay.

I get the same in IE 8.

right click, inspect element, delete
