I'm lost. I've read maybe half of GTD, and spoken with a number of people who , so they say, follow the dictums.

Still, I have on idea why they, or I, would want or need this.

I uses assorted to-d-like things, in particular todoist.com. Stupid easy to store stuf there, pull it out, etc. Mostly I do it from the CLI, or form an Android app I wrote for myself.

Point being, I don't see what problem this solves isn't already solved by several existing apps or services that are set up for easy interaction.
