At scale, a relevant number of your customers talk. One example in TFA is that customers do not have conversations where they randomly recommend operating systems to each other. Well, I'm sorry, but in my bubble they certainly do. I have recommended more operating systems than car models to others.

The other thing the article misses IMO is that detraction is also growth, albeit negative growth (and additionally, people are in my experience much more likely to passionately recommend _against_ something they hate than recommending something they love). So the NPS tells you a thing or two about: - Your potential to utilise whichever chance you have to grow via word of mouth - Your potential to squander that same chance due to people hating your product - Your potential to have negative growth because your customers are leaving in droves.
