I've used a notebook at well and I think you'd be able to work with the same strategy. The notebook is just ephemeral thoughts that you have the impulse to take action on, so you write them down instead of acting on them. At some point you move the worthwhile content to a better resting place. It shouldn't end up being an irreplaceable object :)
