This story strikes me as (at least partly) survivorship bias. It's great that they were able to acquire 600 paid customers without advertizing their product on blogs, and ignoring their competitors. I don't have hard numbers to back me up, but I doubt that this is a successful strategy in general.
This story is a data point that proves that it's possible, not that this gives you a better (or even good) chance at succeeding. Hell, I would wager that greater exposure would have led to much higher sales.
