I also didn't quite get the point of the article, but I clicked on it because I expected to learn some insight about something related to the number of minutes in a day.
Like, what I learned in engineering, that there are 86,400 seconds a day and you can use 100,000 instead for estimation. E.g. when you have around 10 requests per second in a web service, each taking 1KB, then the traffic the web service generates a day is 1GB (== 10 * 100,000 * 1,000).
