Those are all great ways to promote Steemit. I've gotten a few friends to join, and I recently got my mom @doverland started on here! I'm always talking about Steemit and how awesome it is, so once they hear me talk about it a few times they start getting interested. I've got a couple Steemit t-shirts too and that also really gets people wondering about it. I think Steemit is gonna grow to be huge!
