And it looks great on firefox and uzbl (webkit) on linux. The font problem is hardly the fluid's fault.
I’m reasonably sure that this wasn’t submitted so you can critique the font choice. The font has not a damn thing to do with the fluid layout – I think? You could use freaking Verdana!
They look reasonably better on Mac. But Chrome has known rendering issues. Safari (Mac) makes that page look quite pretty.
Yes font look really terrible with FF, i can barely read the text, but with IE it's a lot better.
