I could see how it could be beneficial for some types of tasks in that:

- you avoid clutter, tasks like "fix the squeaking door" which would otherwise stay at the bottom of your list forever are purged

- it forces you to prioritize tasks

- at the start of each day it forces you to consciously plan what you really need done, which is something one may want to be doing anyways to be more deliberate about what you spend your time on

That said, I would probably only use this for non-critical personal stuff rather than in place of trello or tracker.
