Cleartype wreaks havoc on webfonts. Turning it off gives you smooth fonts, but jaggy regular text >:|

Strangely IE6 (and 7? i think) are OK even with cleartype on.

There is a css hack to get font smoothing on windows:

h1{ text-shadow: 0 0 0 rgba(0,0,0,0.0001); /* Transparent Shadow make some kind of webkit font smoothing kick in */ }

I turned Cleartype off and that helped. The text shadow trick helped as well. I would have thought that using Chrome would mean that Google's fonts would have displayed correctly, but I guess Cleartype overrides that. I miss the day when testing a website meant using just IE and Netscape -- now I have to turn Cleartype on and off ... ugh

Thanks for that hack. I'd never seen that one before but font smoothing on Windows has always driven me nuts.

I noticed the same... they have never been smooth on Firefox (Windows 7 64bit), but now they aren't even smooth in IE... can anyone else confirm that?

Most other comments are commenting on the interface, which is definitely great and impressive. As for the fonts, they're not smooth for me either.
