I answered some questions on the Mac Power Users forum about the usefulness of sleep tracking technology. Given that sleep is essential to cognitive productivity, I thought I’d let you know that I followed up today with a blog post on the mySleepButton web site: “Limitations of Sleep Tracking Apps and Hardware“.
Before reading that post, however, I would encourage readers to make a bullet list of their opinion on the subject. Then they can assess what, if anything, is new (potent) and useful in what I’ve written. (An application of the “CUP’A” criteria from Cognitive Productivity books.)
