(I'm the author.) Thanks for the feedback. I agree that the statistics are emotional and not completely translatable to productive time, though I do think the numbers are still significant. Specifically, I think these types of savings compound, so that if you can save one minute of time on each of a 20 daily tasks, then at the end of the day you could have an extra 20-minute continuous block, which is much more valuable than 20 1-minute blocks. Re: .05% -- I personally think mentioning GPD is useful because .05% sounds fairly trivial, but .05% of the GPD is still something like eight billion dollars, which is a very non-trivial amount. Finally, I really like the philosophy of the blog post you linked to, but I think it's talking about a slightly different point. The examples I gave are about a single organization doing something that saves an aggregate of millions of hours or millions of dollars; they are not about trying to convince millions of individuals make a conscious choice to each save one dollar or a few minutes. In the language of the linked post, I would consider the latter to be a million minnows while the former is a single shark.
