Your techniques, as effective as they maybe, aren't really 'Growth Hacking'. I think there is fine line between the good 'ol 'Internet Marketing'(read spamming) and growth hacking. I'm not sure your's fall into the later.

Don't get me wrong, I'm not saying that the things you mentioned will not help you to get more users and eventually make more money. Then again, if money is the only thing you're after, you could as well be making crapware or promote 'Work From Home' guides. Trust me, they can make you a lot of money, I've been there. There's a reason you're making iPhone apps instead of crapware. That reason should be honored.

Anyways, I hope I delivered my message correctly. There's is nothing wrong with what you're doing. Zynga did the same things you're doing with twists on a large scale and made millions. But we don't want to be Zynga, do we?
