If marketing = driving new business/customers, there is no different between "marketers" and "growth hackers."

They use different tools to accomplish the same task. It's time that marketers realize there is more at their disposal.

Agreed for the most part - but are modern-day marketers not aware that there are more tools at their disposal? As a marketing professional, about 90% of what is described as growth hacking is, in my opinion, just plain old marketing. And most of it is pretty understood in my circles - content marketing, SEO, SEM, landing page optimization, etc.

There is a product part of it as well - so my conclusion is that growth hacking is probably more about a different way to think about product management than marketing. The examples given of Hotmail and others fall into that bucket - making changes to the product itself to drive growth.
