I agree, the UI needs improvement. No one feels the gaps more than I do. But they say, "launch before you're ready!" ;)
For one thing, scrolling on its own (with mouse scroll), doesn't automatically highlight whichever card is now centered. So it breaks the flow. Clicking, or scrolling with keyboard are the only way right now to keep the context clear.
> the hyperbole is a bit of a turnoff for me.
I know, it's a big claim, and I don't expect anyone else to believe it. I thought about not including it, but it's honestly what I believe. Delusional founder? Check.
> This is really a different formatter for the same structure of text we've already been using
That's true, more or less. Table of contents, chapter & subsection breaks, etc, are all attempts to make the structure clearer.
However, once we go beyond 3 levels deep, this has significant advantages.
One can get an overview of a text by reading column 1, but can drill deeper and deeper into specific sections, and even into other trees that are embedded (or "transcluded") into this one. We could have all of physics, or comp-sci, in one tree, and the reader will always be able to drill in for more, or zoom out for overview.
> Why do we need something new? What's being added? What couldn't I do before that's now possible?
There are great benefits for writing this way, for one. Rearranging entire sections or subsections is just a drag and drop. Working collaboratively is also easier, because each person can focus on their particular strengths
> Hopefully this criticism is helpful.
It is, thank you. All criticism forces us to reevaluate our approach, again and again.
