The Obsidian PKM Builder

A researcher, writer, software developer, or knowledge worker who has built their second brain in Obsidian and means it. They write in Markdown. They link notes intentionally. They have a vault structure they've iterated on at least twice. They use the graph view occasionally, for the pleasure of seeing their thinking made visible, not because it's the most useful view. They've installed 8–20 plugins. They have strong opinions about the right way to take notes, opinions that evolved over two years of using the wrong way.

“A teammate asked how they managed capture ideas in a format that connects them to related ideas automatically.”
