I wonder why. There are plenty of ways to get growth, why is this one so important? I can think of one reason off the top of my head: Perhaps it's because many organizations that grow very large do so by creating a market, or largely shaping it in some way. It seems that in that case, word of mouth is even more important. As an example, I tell my friends about gyro food trucks all the time. But most of them have decided whether or not they're going to eat greasy falafel. On the other hand, if there's a new type of food vendor they've never heard of before, it will count for a lot more, because their opinion hasn't been formed yet. I suppose the other explanation is that word of mouth is only a signifier of high quality, but I'm not sure that's all of it.
