I fail to see how much of this is that useful to most startups. It seemed more about how to create and push mass amounts of spam in the hopes of hitting it big. I didn't see much in the way of actually increasing your interaction with potential customers. It's just a numbers game about how many eyes can I get in front of hoping something works.

I'm sorry, but I just cannot possibly take someone who uses the term "growth hacking" serious. Much like job postings using "ninja" or "rockstar"; it's just a blatant attempt to appear cool or hip in a strange way.
