I agree with the author, but the irony is that resurfacing is akin to UI friction. I resurface content in a journal because I have to flip pages to find the content I seek.

I've emulated some of the features the author wants in my obsidian using Dataview, but it's more the human ritual of review that accomplishes this for me.

I do agree, there is a good product there.

Indeed, I wonder to what degree these problems would be better solved by a habit of exploring what you earlier wrote, and having categorized it well, and constantly recategorizing. The power of writing is not in the initial draft, but in how one wrestles to understand that content.
