Great comments and I'm going to upvote you! I really like the more subtle approach that you suggest. So here is what our pitch looks like now.

Hey, check this. I joined a website recently called Steem.com It's pretty neat, you can and will earn money just for interacting with people. However, the best way to make money is to be a content creator. Just like being a YouTuber.
Each time you write a post or comment on someone else's you actually get paid in a digital currency called Steem dollars which you can easily convert to US dollars.
From finance to photography there is heaps so it's my goto social media site now!

....we now need some more people to contribute to this to get the perfect pitch!
