This is a guest post by Raoul's brother Etienne, who is not only passionate about fonts and typefaces, but also open source software.
Any modern operating system includes a wide selection of typefaces so that one can get working immediately. Windows comes with its ClearType fonts installed by default, including the award-winning Calibri, while Apple’s OS X has included the coveted Helvetica ever since it was NeXTSTEP back in 1988.
But what about those of us who choose free and open-source software? How can we ensure that the typefaces we use are free from proprietary restrictions? How can we share our fonts with our friends freely and legally? And, most of all, how can we make those using proprietary software jealous of our beautiful documents and publications?
I have thus put together a list of my top 10 free or open-source typefaces. While there are indeed a large number of fonts available free of charge, I have ensured that those listed here conform to either the Free Software Definition or the Open Source Definition.
