I just skimmed the manual, and I love it! This is extremely similar to how I envisioned trying to write a TeX "next generation", almost 15 years ago. Standout features, according to me: - lightweight - built on modern technologies (TrueType fonts, PDFs) - high-quality output - lets you separate content & presentation if you want (XML can contain content, .sil/.lua presentation) - lets you create page templates that text flow onto. (like InDesign) - lets you write packages to do tricky things, and has validated the programming model by solving some legitimately hard layout problems. I'm not in academia and have never found TeX's ecosystem of packages a huge draw, so I don't think I'll miss that much. The main thing I worry about is stability of interfaces. If people start writing documents and packages that target this, will they continue to work in the future? Is the developer committing to that? Overall I'm really excited to see this!
