Same, except I append to the bottom of an Apple note. (I append, the author's really prepending. Anyway...) When the note gets too long, I cut and paste it to what I call the big note: a 127000-line, 4.9 MB text file I've been maintaining for 14 years. Trivially searchable, can get context from neighboring notes (What else was happening around this time?), and easily parsable when necessary.
