Currently, i use Obsidian mostly as a glorified file manager. It lets me annotate directories and files, I can add data fields to selected entries and I can search the directories and notes very quickly. Also, the assistant which fills in internal links makes connecting notes nearly painless.
I originally decided to try Obsidian because the information resides in files and the MD files can be used after a fashion even if I decide not to use Obsidian any more.
