First off I want to thank you @timcliff for this incentive. I'm in full support of promoting steemit and I currently carried out a promotion myself on the Utopian. io platform.
I carried out my promotion on Facebook where I created named Utopian-io promotion page. I intended to kill two birds with one stone (promote both platforms) because any user who intends to join steemit must also be a registered member of the steemit community. I created a paid ad in which I promoted the platform and directed the users to the link.

So I got to reach 5242 people with my budget and the post engagement was pretty good.
So I can say I successfully Shilled steem.☺
