Another aspect of PKM in this question is that note titles can have front matter and back matter, just like note content which adds value. Using characters, symbols, emojis, or numbers at the beginning or end of a title is another layer and aspect of a note-making system, much like tags or links—another tool in our note-making utility belt.
Note title front and back matter use, function, and value should be included in the discussions and teachings in the LYT kit as another facet of a PKM system. Yes, using them is an individual choice, part of the personal aspect of PKM. Still, the LYT kit should address this principle regardless of whether the numbering is retained or not. It is a part of a note-making system that folks should understand so they can decide to use or not.
The Home note is my highest level of emergence. The front matter titled numbered MOCs the second level, and the plain back matter titled MOCs with the MOC designation is the third tier. Besides the ordering that the title front matter provides, these note conventions give a visual frame of reference when I interact with a list of note titles in the note list, search results, or file system, even in the graph view to a degree. These levels could be designated in other ways without using title front and back matter, such as tags and work, but you lose the visual references.
The LYT kit should include the concepts of the title front and back matter, much like the “art of link curation.” With the main maps note titles losing their numbers, it may be harder to accomplish.
Why not drop the title back matter identifier of MOC? All the same arguments for removing or keeping the acronym are just as pertinent. The numbering and MOC acronym are unique to the LYT Kit, its creator, and its community. Without them, a vault or a folder of notes looks like an ordinary joyless folder of files. The Mona Lisa without her smile would be just another portrait by some old 15th century Italian guy.
Do not include, a disturbance in the force would be!
