Firstly I must say that I love the construction of words, ✌️👏👏👏

You have highlighted several ways to promote Steemit, but about rewards, here are good rewards on the platform, but it comes with a price, and the price is a hell of work and providing ideas to the growth of the platform, whoever is active on this platform, I guarantee the user vote, because all they see are people who are actually invested in the platform beyond reward so that been said in my own humble opinion is what I think, but the promotional idea will definitely onboard a lot of user if implemented.

Greetings and blessings
