My thoughts are so all over the place that I've settled on 3x5 note cards. It also makes the transition to the computer much easier, because I can re-arrange them in a way that is somewhat organized before taking a picture that gets transcribed
Scrivener just matched my workflow - usually for technical reports. Lot of cut/paste from a variety of sources.
But how do you archive these cards? That always drove me mad so I use them only for something “encyclopaedical” otherwise it is too much messy.
It's mainly the capturing of the ideas that I prefer writing physically. After that, being able to move them around my digital system makes them most useful because I can have dynamic views that surface priorities and related notes without having to physically sift through the stacks.
