"something about the overall tone of the docs and Cozens' web presence would discourage me from making an investment of time in one of his projects." I'm not sure I understand that assumption. He's been around the OSS community for decades (wrote some O'Reilly books about Perl, and wrote quite a few Perl modules, though that was more than a decade ago, and I dunno what he's been up to since). I do find the github a little sparse, but there is a website for SILE, which is better: http://sile-typesetter.org/what-is/ http://sile-typesetter.org/what-is/ It looks like a personal project, rather than a "take over the world" attack on TeX. Seems like if it's an area that's interesting for someone, they might want to have a look. It does have some novel ideas over TeX, and is maybe more modern in some of its implementation details, even if it is nowhere near as complete or mature as LaTeX.
