I’m just getting started with Obsidian. But this kind of thing is precisely what draws me.
As I see it, a decentralized MOC shares an organizational structure with folders—which I’ve been using my whole life—or hierarchical tags—though I’ve never used tags much until recently. But there’s the added value that you can have context and additional information in your MOC, which you can’t have as easily in a listing of folders and documents.
Klaas nails it in this use case
Or, in my case, with project management: Have an MOC for each project, with links to every document, which can include notes, PDF, Microsoft Office Documents, email messages, etc. The MOC and each item in the MOC can contain a line or two of description or summary—not easily accomplished in the Finder/File Explorer/File Manager.
I’m calling my MOCs “Dashboards” because I dunno I just like how that sounds.
