I actually stopped using Obsidian a few months ago. I feel like these knowledge collection/note taking applications over complicate everything. I wasn't happy with the search feature in Obsidian specifically and the fact that it forces you to add their own application specific characters/flavor to your markdown. [0]

I thought about it and my minimum requirements for a knowledge graph tool are:

1. Edit files in vanilla Markdown (no application specific cruft)

2. Be able to search content easily (ideally via grep)

3. Add 1:1 or 1:many links between files (direct links vs. tags, ideally using requirement 2 to implement this)

And the simplest solution for me was:

1. A single level directory of md files (no folders!)

2. Vim + Telescope [1]

3. A small set of guidelines [2] to define searchable patterns for linking files/nodes

I also wrote a little md renderer (seen in link 2) that adds the features I wanted for exploring my notes/second brain in a browser that picks up on the patterns in the guidelines. Gotta get a grep search on that thing and it'll be golden, but I apologize I'm rambling at this point.

Never been happier. I just use Working Copy to jot notes on mobile when I'm not at my computer.
