Am I or are you a growth hacker?

Growth hacking is a new term to me and seems to be to most of us in this forum. At the same time, on Twitter growth hacker seems to be comparable to digital marketing specialist in scale as far as people use to describe themselves.

After reading http://www.warriorforum.com/growth-h...th-hacker.html, I am wondering if I am a growth hacker and if you think you are and why?

Many of us on this forum have thought of ourselves as "internet marketers" or "digital marketers" but it seems now the term growth hacker applies much better to me and anyone that uses a combination of data, creativity, and learning (curiosity) as the foundations for what they do.

The article I cited above says growth hacks are usually inexpensive and there is where my personal conflict comes into play with calling myself a growth hacker. The short version of what I have done online in the last three years is pioneer ways to use paid ads to make a huge audience in the millions using data driven targeting options to audiences most people think are worthless such as those from third world countries. While this includes the three principles of being a growth hacker as described in the TechCrunch article at Defining A Growth Hacker: Three Common Characteristics | TechCrunch, much of growth hacking is premised on doing things from free.

The question then is where do you decide that you are a growth hacker instead of a digital marketer or an internet marketer? Based on the data, I would have to say I am a growth hacker but the term is so new to me I am not sure if I should change all of my social media profiles right away until I talk with a few of you guys to see what you think is most important or least important about your own decision to call yourself a growth hacker.
