memo VS zim-desktop-wiki

If you're giving Foam a look, also consider svsool's unfortunately named "Memo" (previously Markdown Memo): https://github.com/svsool/memo It's a VSCode plugin for groups of Markdown notes similar to Foam and Dendron and inspired by Roam. I prefer this to Foam.

I'll slightly modify your argument; because Pure HTML does suck:

Why don't people make static sites with a simple "Markdown-or-Similar to HTML" converter, CSS, and vanilla JS...etc?

(This is what I do, btw -- http://zim-wiki.org + a template)

You should add Zim [1] to the "Personal Knowledge Management" section :)

And I just tweaked the CSS and added a bit of logic to included the possibility of one image per slide; as well as editing slides not with raw HTML but with https://zim-wiki.org (because that's what I'm really used to, I'm sure any Markdown thing would work just as well).

Absolutely; recently I realize I wish I'd never learned vim. I use too many other programs that are at least CUA-ish ( http://zim-wiki.org is the most important app I use ) and now I kind of want out. I haven't yet tried Modeless Vim, but that looks like my next experiment.

It is so hard not to feel REALLY SMUG reading stuff like this, as someone who has run my own website as the working primary source for my college instruction for the past 15 years or so using https://zim-wiki.org. (before Markdown was much of a thing!)

It's borderline bizarre to have watched this method of doing things kind of die out, and then also come back in the form of "static site generators" -- which, frankly, are still way clunkier than this.

Write in Zim, export to html, rsync to site. Easy.
