Open Sans is very nice looking OPEN SOURCE font, now employed in WordPress.com sites
If you’re sharp-eyed, you’ve noticed that we recently adopted Open Sans as our default typeface across WordPress.com.
Type wonks know that Open Sans is a humanist sans-serif typeface. It’s elegant and sophisticated, yet modern. It’s beautifully legible, offers an excellent reading experience, and has a superior typographic range that includes accents, non-Latin characters, and more.

Open Sans, designed by Steve Matteson, Type Director of Ascender Corp, isn’t just a pretty (type)face: it’s free and open source, just like WordPress! It was optimized for print, web, and mobile interfaces. We know you’ll love it as much as we do!
