Already doing that and have been asking all the people I know to look into getting a card, getting them onto Steem if they aren't already here.
From what I know, there are over a dozen people with cards on Steem who are promoting the idea within their circle of friends.
I will gladly use anyones referral link in any promotional post here or Twitter or any other site I hop onto.
Sharing the wealth is always a great way to get people motivated.
Cheers mate.
