Personal Knowledge Management (PKM)
Personal knowledge management (PKM) is the practice of systematically capturing, organizing, and retrieving the information you encounter, so it compounds instead of evaporating. Typical PKM tools include Obsidian, Notion, and Readwise.
The discipline behind the tools
PKM is a workflow, not an app: decide what's worth keeping, capture it with minimal friction, organize it lightly enough that you'll actually maintain it, and review or link it so it resurfaces when relevant. Tools matter less than the pipeline between them.
Saved content as a PKM input
Social saves — Reddit especially — are most people's largest untapped PKM source: already curated by your own judgment, already labeled by community context. The failure mode is capture without transport; automated export from where you save to where you think is what turns saving into knowledge management.
