Maybe this is saying the same thing, but I interpreted it as "If a handful of developers write an application that millions use, then saving a few seconds per user can add up." I've seen this applied to the Linux kernel, where saving a few microseconds in a system call, when multiplied out to the billions of machines running Linux, saves hundreds of years of CPU time. With that said, most services don't have as many users as Linux.
