I never intended to imply it is an emergency condition. 1M users is in fact an enormous accomplishment, and I had exactly your theoretical business in mind when writing it. Not the one with no business model, but the one making 1M year.

I was just trying to say as you said that unless you have significant organic growth, "it's going to be a long slog to go from 1 million users to 10 million users." A much longer slog than people think when they reach that point and are planning to re-investing in traditional channels. A great 20% growth rate only gets you to 6x in ten years.

Dropbox is the counter-example. They've grown viraly.
