“System Font Stack | CSS-Tricks”
More sites are using system fonts than you think.
@baldur btb: Ubuntu is a rather horrible font, compared to Dejavu Sans, Droid Sans and even parts of Open Sans. The aforementioned fonts are also major linux system fonts, and I'd rather see them everywhere (preferable the first two) than the Ubuntu system font. They say it's a relative of Futura and Helvetica Neue, but it still got some waay too ugly edges .. Droid and Dejavu Sans are much more precise and refined, compared to that. /1
