This approach works well for knowledge pockets where the discovery of application of knowledge is naive. When you want to extract a tar file and don't remember the command your brain know you have saved the command somewhere in a log and you can find it. But think of knowledge areas where you have to connect a few different learnings together to form an intuition on the application of knowledge to a problem.

For stuff like that, I think that I keep the intuition without having to write it down and review it later. But I could be mistaken. If I don't use the intuition often enough to keep it available in my mental toolbox, then I don't use it often enough for forgetting it to be a major loss.
