Yikes, the font on that website is incredibly distracting. Hard enough that I went and downloaded Readability for Chrome just to get through the article.

Reading more than a sentence caused my eyes to sort of glaze over and even when trying to focus I was reading but not grasping. Can't say I've ever had a font do that to me.

In cases like this, you can just "inspect" on the text block, find the rule for the font-family and set whatever font you like, no need for extensions :)

firefox reading mode (i believe it's the same devs as that chrome extension? icbw) is the first button i press on most sites. i couldn't do without it.
