Your site is more "minimal" in that it has fewer text elements on the screen. But your site is much harder for me to read than gwern's. First, I hate dark background, white text; white background, dark text is much easier for me to read. (Note that gwern's site gives both options.) Second, your background image is a huge distraction for me, as is the weirdness of the non-image background at the top and on the right. Third, your paragraphs are right justified instead of left justified, which I find distracting. Fourth, your font is too small for me to read easily.
The upshot of all that is that I read the entire content of gwern's page. I didn't read more than a few headings of yours.

Unintuitively, this is a success for me! The headings clearly stuck out, you were able to quickly scan them and determine you didn't care to read the details. That's how I'd expect a minimal design page to work.

That's not what happened. What happened was that after trying to scan a few headings of your page, I was so put off by the site design that I didn't even bother trying to figure out from the content of the headings whether I wanted to read the details. So your site design prevented me from doing what you describe.
