The hubris of the statement is not lost on me, but what should a founder be but delusional and optimistic :)

1. It's both a viewer and a word processor. It relies on Markdown (and LaTeX through extensions). We export to Md, but will be adding more import/export options in the future. We hope to create a publication standard for it.

2. The structure of the document is an "outline of index cards". Each card can have one or more children. Source content (in markdown) is edited by toggling edit mode on that card.

3. Yes, we are extracting parts of this as open-source. The rest remains proprietary (for now, at least).

> I apologize if any of the above seems harsh

No need to apologize. Thoughtful criticism is what we need.

Thanks!
