I have to confess I was partly inspired by ZK to start doing this, but by doing it for transitory notes and putting it into my day-to-day habits I feel like I've gained super powers. It's less effort to use a timestamp as a UUID for everything and I don't have to think about how to organize them until natural patterns emerge which I can sort by with lists, or refine into a more focused note. I can also remember roughly when I was thinking of something, even years later, and zero in on the note based off of that if I can't find it through links or lists.

ZK, to me, requires a lot more focus and energy. It's not very well suited for, say, taking notes while you're on the phone or in teleconference. They aren't mutually exclusive, they just have different uses (I also have a ZK).
