@writingslowly I enjoyed this. Thanks for sharing!
@writingslowly I pretty much do the same as you suggest here, although I find it useful to have a small number of sub-categories of permanent note, as described in my post linked to below. The idea is that certain sub-categories of note are more complete than others, so being able to see which ones are less complete is a useful indicator of notes I might want to develop further. (A year and a half after writing the post, I haven’t felt the need to amend my ‘tagsonomy’, so it certainly seems to be working for me.)
