Force chrome to use my preferred font over the author's
I'm pretty comfortable with a chrome extension called "Read Mode" very readable. A drawback is improper display of quoted text. So I'm sticking with it till I find a better alternative.
Edit: Find out another one, it is a JavaScript bookmarklet, put the following line in the location bar(where you put website adresses like www.site.com) and hit ENTER :
javascript:Array.prototype.forEach.call(document.getElementsByTagName("*"),
function(e){e.style.fontFamily ="Source Sans Pro"})
Replace Source Sans Pro
with your preferred font.
If you don't want to type this every time, bookmark it and click on it whenever you try to change the font.
