I've done all my planning and note taking using plain text files for years, and never had the need for these complex tools. I tried Roam and Obsidian because of the hype, logging and connecting everything I read for a few months, but then I burned out and realized they don't help me at all. Most of the value from note taking I get is by writing notes, not by managing them or looking them up later. I'd almost never look up stuff again so all this management effort is wasted. And if I need to find something I can either use Google (no need to keep track of links) or it's so obvious that I can do a simple text keyword search through my notes.
Can someone explain why these tools are so great?
