Dennis O. Smith wrote in with this question about Unleashing the Ideavirus: “I understand the concept of spreading the idea, but how can you control or direct that growth? ‘Going viral’ is great for fast growth and sharing of your idea, but are there mechanisms to steer it, trim it, shape it, etc.”
The reason that so many people catch a cold every year is that no one is trying to control where it goes. The reason that Wikipedia is so robust is that control is decentralized. The reason that there’s a huge disconnect between corporate marketing and ideas that spread is that the culture of contagious ideas is anethema to the command, control and responsibility mindset of the industrial marketer.
