To be honest, I have long since given up on any kind of "generic" efforts to draw new people to Steemit. I share occasional posts "outside" and if anyone asks, I'll tell them a bit about why I publish content here. I think a few have signed up; I know only of two (over 10 months) who have actually been active to any degree, and one of them is my wife.

Mostly, though, my "sales" approach is to market Steemit to people who are bloggers and content creators. I have zero interest in pursuing "income seekers" since they often are the primary spammers.
