Question

I'm in my fourth year of University and there are a few mistakes that PowerPoint enables lecturers to make that drives me a bit crazy.

Unsearchable documents (like a PDF made of jpegs)
Uncopyable documents (at this point I take photos with a snipping tool and paste them)
Not defining variable in equations (I'm imagining tool-tips when hovering over variables)
Not enabling students to make corrections or augmentations (like pull-requests on GitHub)
Platform dependant viewers (like Word)

Obviously the only media format to achieve this is HTML. Has there been a tool created that allows a lecturer to not fall into these traps and that uses easy WYSIWYG editing? Does it have a publishing platform that makes it easy to share, correct, reference and licence these notes? Most importantly, can diagrams and equations be inserted easily and edited/remixed easily?

Explanation / Answer

Check out Knowen.org! Its development is motivated by the same problems as you describe. Features:

Text is formatted in Markdown, LaTeX math is supported
WYSIWYG editor
Searching
Easy article editing and commenting
Organized, linked document structure

The portal is under active development now. It currently lacks features like exporting to LaTeX and PDF (only downloadable HTML now, though one can convert it with third-party programs) or convenient picture insertion (image hostings are a bit annoying).

Full disclosure: I'm one of the developers of Knowen.
