I have a good friend I know this would certainly apply to. However, if I just send him the link it will come across as criticism. I'll have to stealthily slip it into conversations over time. Sort of like changing culture at a company. It won't work by firing off links to everyone - at least where I work. Will need to sneak it into converations.
