“Your email is about to be sent to several hundred thousand people, who will have to spend at least 10 seconds reading it before they can decide if it is interesting. At least two man-weeks will be spent reading your email. Many of the recipients will have to pay to download your email. Are you absolutely sure that your email is of sufficient importance to bother all these people?” – Poul-Henning Kamp, circa 1999
