Not to be mean but the site's fonts look absolutely horrible on Chrome 20 in Windows 7. The top ones look messy and thick and the bottom one looks much too thin:
The fonts on this site look worst in Win/FF. They're not great in Win/Chrome, but at least they look well matched. It looks good in OSX/Chrome. Probably because that's what it was developed in.
Protip: different browsers render fonts differently. Test your site before you release it into the wild.
