That's one way of getting people to to this platform, however I highly doubt my $0.03 upvote will be incentive to someone to join us here. You can also make a coin that has some special mark on the back, and it will always give upvote from original creator. That way, 1 coin made by you could get dosens of new users to platform.
I found a way to contribute to your idea, here are 2 memes I generated. Anyone feel free to use them and dont forget the #getyourasstosteemit tag.
