PKM stands for Personal Knowledge Management. It's a fancy term for "taking notes so you don't forget stuff."
Tools like Obsidian, Notion, and Roam Research have exploded in popularity. They are great for private thinking. But there is a missing piece: Public Learning.
The "Second Brain" is Lonely
You can build the most beautiful Obsidian graph in the world, but if it stays on your hard drive, it's a silo.
Ideas grow when they collide with other people.
Microblogging as "Working Out Loud"
Jottings is the bridge between your private notes and the public web.
- Private Note: "Read about the Zettelkasten method. Interesting idea about atomic notes."
- Public Jot: "I'm trying out the Zettelkasten method. The concept of 'atomic notes'—one idea per note—is changing how I write. Here is a link to the guide I'm using."
The Feedback Loop
When you publish a jot, you get feedback.
- Someone replies with a better resource.
- Someone asks a question that clarifies your thinking.
- You search your own site 6 months later and find the answer.
How to Start
Don't try to publish your "finished" thoughts. Publish your "in-progress" thoughts.
- Read something interesting? Jot it.
- Solve a problem? Jot it.
- Have a question? Jot it.
Your blog becomes a public log of your learning journey. It is the most valuable PKM tool you have.
