Skimming through this, it looks more like organized public bookmarks. Many of the pages just contain (mostly) a list of links. There are barely any notes.
I actually do this as well. Just some text files, where I put links I stumble upon, which I find interesting. Not always all links but only really interesting ones. Also maybe only for topics where I think it's not so easy to find such links later on via Google. Also, I don't really intend this to be complete.
Sometimes I also do research on some new topic, and for that I keep notes. If I think the research / overview / my notes of this topic are of any value to others, I would maybe just make it public somewhere.
Some of these links and notes I keep private. If it is public, I would probably just put it here:
