I'm not so sure giving him Nxt would be a good idea. Bill Still took a lot of heat for possibly receiving donations before he promoted Quark. I'd rather not risk the accusation of the Nxt community "bribing" him to promote Nxt. Just give him good information with no strings attached, and he'll appreciate the gesture.
Yeah that's probably the best way. Let the guy decide if he likes it or not. Good information would likely be best.
We want to give him something to entice him to use Nxt. I give Nxt to a lot of people. Is that a bribe? No. It's just a friendly gesture. "Hey. I think you might like this. Try it out!"
