Great job. Amazing post. At the very least you clearly got someone who has influence and an audience interested in Steem. He seems genuinely interested, as well he should be. Everyone on Steemit should take serious lessons from this post. Absolutely perfect. The key thing you did was did him FAVORS. You did stuff to genuinely help him. That's how to market. You don't deceive or guilt people, you do something for them in the hope they will then be open to doing something for you that is mutually beneficial for your both.
