Well, if you look at the snippet behind the URL Google gives you to use, it reads (for me -- it appears Google does browser sniffing to not serve Firefox IE-specific workarounds etc):
@font-face {
font-family: 'Nothing You Could Do';
font-style: normal;
font-weight: 400;
src: local('Nothing You Could Do'),
local('NothingYouCouldDo'),
url(http://themes.googleusercontent.com/static/fonts/no...YU.woff) format('woff');
}
Lose the two local
bits and host the CSS yourself, you should be better.
