This! My first actual project (besides some testing) has been my phd manuscript, and after ~2 days i actually had a tufte-style 1.5 column layout going, written from scratch. And its probably like ~250 lines. There are some rough edges still, the dom model and advanced programming stuff is not quite there yet (user-defined elements, user-defined settables, advanced layout like chaining blocks for laying text flows). But like the quality of the user interface is several orders of magnitude better than (La)TeX.
