If the goal is later reference (not task generation), the most useful thing to validate for me is: what “organized” means in practice for you. Is the biggest failure mode:
1. you can’t find it because you don’t remember the right keywords, or
2. you remember it exists but it’s scattered across too many places/notebooks, or
3. you find it but it’s missing the surrounding context?
Details in my HN profile/bio if you want to see the angle I’m exploring (it’s not only Obsidian-specific).
