Back in a previous post about Obsidian, I mentioned that I was paying for Notion, and Clickup. In an attempt to reduce my overhead costs, I had initially started using Obsidian as my main PKMS (Personal Knowledge Management System — I didn’t make the acronym up, there’s a fantastic sub-Reddit you can find at r/PKMS). I have since been bouncing between Notion, Obsidian and a newcomer, Affine Pro.
