Hey man! Very glad to hear that you liked it! And yes, this post for me has been years in the making, and ties together so much of what I believe are important pieces of the puzzle to make Steem a success.

Well, the referral program will take its course naturally in the sense that people are free to try to onboard whoever they want. I don't know myself in what content categories we have the most passionate ambassadors for Steem. So will have to see. We ourselves will be targeting specific growth segments that we believe are more likely to want to come onboard and who bring more value. Making the effort more focused can have 2 benefits: 1. It is easier to get familiar with one niche at a time in terms of learning where they are easily reached, what expectations they have, what an affective pitch therefore is, etc. And 2. because growing one topic at a time means those you onboard find other creators relevant to their niche and whose content they may like to consume themselves, rather than being an island amongst others whose interest you don't share and thus don't get a lot of engagement on their content.

In any case, if you yourself or anyone you know would like to get involved in the referral program, then do reach out to me!
