I really like these in depth, detailed note taking strategies/tools, but I've come to just using markdown files with good naming. Even then, I'm getting annoyed with myself splitting up class days into separate files. I think I may even just go back to plain text.

I use markdown because it looks great when rendered to HTML, but I've only ever used my rendered notes once in three years. I always just grep them or vim search them instead. Since I'm not getting a benefit from markdown, I'm just going to switch back to text files, using one per class for the rest of the semester and a separate file for misc topics/notes.

I think I'm just not the audience for this, but I like the concept of these detailed note systems a lot, I'm just not very often searching my notes again without just using plain old grep.
