While these are great concepts, I find it to be an overcomplication for my needs. When we build systems of any kind it's nice to imagine the ways in which they make our lives easier, and we always underestimate the required maintenance of our systems and the ways in which they come to constrain our thinking and action.
I have a pretty simple organizational structure for information: I keep text files on ongoing projects and ideas. I think on ones that are on the back burner and update my notes on them when I have something compelling come to mind, and the forefront ones or ones that are related to maintenance I keep accessible, usually on my desktop or always open in my text editor. It's a bit of a disorganized system but it is just the right level of complexity. I'm the kind of person who knows which pair of pants on the floor that I left my wallet under last night and so a good portion of organization exists in my head and I work better that way. I'm always on the lookout for new organizational tools, but a huge criteria for them is that they require little to no overhead or maintenance.
I do rely on online search a little too much, I often forget to store information I find and might need later and instead store my google-fu queries in my head, and because of that often times I cannot find it again later (because online search as a tool is degrading as we speak) and this article is a good reminder that I cannot rely on external tools like that that I have no say in them continuing to work the same way.
