Very interesting to read among other things the colophons, the reationale for a dedicated font and the space given to font-related items: foundries, webfonts, font management, design workshops, etc. A great showcase of promising community work in that area indeed!
BTW the article was titled "freed fonts, stronger web" and is not about "free fonts" a rather loaded expression referring to freeware don't-modify-fonts and NOT the same as libre/open fonts.
