> I think the right initial metric is “do any users love our product so much they spontaneously tell other people to use it?” Until that’s a “yes”, founders are generally better off focusing on this instead of a growth target.

It all comes back to this. I was listening Aaron Harris' interview with Digital Ocean's Mitch Wainer on Startup School Radio the other day (phenomenal podcast). Wainer mentioned how people actually love Digital Ocean, and how rare it is for that word in particular to be paired with the name of a company. I think it's said so often that it can easily be glossed over, but that word is not chosen lightly. Having a product users actually love is extremely difficult, and extremely rewarding.
