I use this book-marklet to fix pages that decide to use a small font weight, that results in this hard to read text:

javascript:(function(){var%20all=document.getElementsByTagName("*");for%20(var%20i=0,max=all.length;i<max;i++){all[i].style.fontWeight='400';};void(0);})();

Fixes those broken pages to be quite readable.

I sent the guy a note last night and he changed it. Very easy to read now.
