I know for me, writing on a page forces me to commit to a spacial organization for the information— partitioning it into lists, leaving blank lines where I think there's going to be more to add, drawing arrows and connections and so on.

Digital notes don't have any of those constraints, so I don't have to be nearly as disciplined about it. But counterintuitively, this doesn't generally lead to me going back and "cleaning up" my digital notes into a properly organized reference; instead it just stays a garbled mess.

Kind of like how I can't do cardio as its own activity, but I'll happily commit to an 8km year round bike commute. I can only get the benefit when it's a forced side effect of something else.
