You know, I also have been struggling with this subject. I just found Obsidian recently, and I cannot fathom how I have not found it sooner! I have spent years taking notes in various apps and trying different systems. Obsidian appeared on the surface to be a very difficult program to use until I realized it is basically a notepad app on steroids?
So I am now trying to find a better methodology to take notes, manage my knowledge, and keep up with everything else that passes through my awareness and needs cataloguing or storing.
If I am understanding MOC’s correctly, my impression is that they are more like smaller indexes to information that branch off others, which in turn perhaps branch off a master MOC?
I also seem to be struggling with the nuts and bolts of applying MOC’s to my own data. I have a few root folders with category names, and under them further folders with notes. So Should I have everything come from one Master MOC in my root directory that links to all the folders in the root directory and then branch from there?
If any of these questions is answered in the documentation, I am still working my way through it. I keep getting distracted by great information and articles, so it’s a slow journey so far.
