One of our Rotterdam reporters made us notice Inconsolata, a monospaced font designed by Ghostscript maintainer Raph Levien. Levien offers an OTF version, plus 'raw' fontforge files on his webpage.
First and foremost, Inconsolata is a humanist sans design. I strove for the clarity and clean lines of Adrian Frutiger's Avenir (the lowercase "a", in particular, pays homage to this wonderful design), but also looked to Morris Fuller Benton's Franklin Gothic family for guidance on some of my favorite glyphs, such as lowercase "g" and "S", and, most especially, the numerals.

Scribus uses the Gutenberg text version of Multatuli's Max Havelaar. The English default is Bram Stoker's Dracula. Of course you could select your own preferred source!
