I love the growth idea! As my Steem Power grows, I'll definitely have to come up with something similar. Right now I've been spreading word about Steemit to my nerdy friends (with very little success).
I've found myself starting to spread the word to some of my less nerdy friends too. While none of them have "taken the leap" just yet, I have received a little more traction from them, so I'll slowly keep at it :)
The challenge / fun about Steemit is that once you have a following, you're not done there. You have to continue providing useful and interesting content to continue to grow! I really enjoy that part about the platform and am looking forward to becoming a Steemit Pioneer!
