Just a quick tip for those of you who are on a browser or OS that doesn't make it easy to see highlighted text. e.g. Chrome on OSX<p>Paste this in your console. It makes every text black.<p>d=document.getElementsByTagName('font');for(i=0;i<d.length;i++)d[i].color='#000';<p>Or make it a bookmark...<p>javascript:(function(){d=document.getElementsByTagName('font');for(i=0;i<d.length;i++)d[i].color='#000';})();
A more elaborate solution is to install a userstyle (<a href="http://userstyles.org/" rel="nofollow">http://userstyles.org/</a>) and a browser plugin like as Stylish. There are dozens of themes available related to hacker news: <a href="http://userstyles.org/styles/browse/all/hacker+news" rel="nofollow">http://userstyles.org/styles/browse/all/hacker+news</a>.
