-webkit-font-smoothing: antialiased;
in your CSS (http://maxvoltar.com/archive/-webkit-font-smoothing)
I've yet to come across an instance where antialiased is better than using subpixel hinting.
In addition, I think it's crazy that the browser would allow a site designer to alter such a highly OS- or even machine-specific setting.
Heck - there's even special tuning wizards in most OSes to configure the subpixel hinting perfectly for a specific monitor.
Dear designer, turning that off for everybody just because you didn't manage to configure it correctly on your machine is egoistic and, IMHO, plain stupid as you make everyone suffer for a thing you should fix at your end.
