Interesting. For some time now I’ve been toying with the idea of making a project for community-sourced, uncopyrighted books for schools. The current situation in the school book market (expensive, paper-only, teachers may not copy, etc) is simply disappointing. But I could not figure out what format would be the easiest to use. I considered LaTeX, since it’s a de-facto standard (and very powerful), but it also has a very steep learning curve. If there would be a good support for all necessary features in a Markdown dialect, that would be awesome.
