My current setup is having both a private Second Brain and a public Digital Garden (see differences between the 2 concepts).
My Second Brain grew large over time, yet no notes were ever published (related Cult of Done). Then I learned about Digital Gardens and I fell in love with the idea. Why should I write for an audience when I can start to write for myself. The idea is that I publish notes without making them perfect. They are notes after all, not scientific papers.
Getting Things Done, as well as most of my personal journaling and Alignment will stay in My Second Brain. But my generated knowledge and connected ideas will slowly go from Second Brain Resources
folder to my Digital Garden.
