I still use Obsidian for meeting notes and other notes, but I keep my Zettelkasten on paper, like you. A6 slips in a box. It's harder to maintain, but that makes me more conscious of what I'm doing.
I tried searching for lootitooti, Vectara found nothing, Algolia found two results, one in a post and one in a comment in another post.
PS: no, lootitooti is not my project. I decided to finally watch Game of Thrones with my wife and I remembered that site when I was watching the opening. I remembered seeing it here on HN, searched and found it.
I kind of understood Zettelkasten only after I implemented it with slip notes in analogue form. I had read How to Take Smart Notes, zettelkasten.de, watched several videos, etc., but I only got more confused. Then I read Antinet Zettelkasten, by Scott Scheper, implemented the system on paper, and finally I understood the system. Now I could go back to Obsidian and implement my Zettelkasten in Obsidian again in a way that would be much more straightforward than what I had tried the first time (and honestly, sometimes I think of doing that because of the convenience of digital). But I enjoy writing on paper and using my fountain pens.
The original title is more click-baity: "A $5 Investment That Will Help You Make Great Decisions"
I never used a decision journal before. Has anyone experienced an improvement in decision making after using a decision journal? Conversely, has anyone tried a decision journal, but felt it was a waste of time with no improvement to the quality of the decisions? How do you measure that quality?
