The #bitcoinpizza challenge was an attempt to help the community think more about the nature of money and where it comes from in the Steemit ecosystem. It's a tough question, and I'm very grateful to those of you who took up the challenge.
Putting this out there was risky for me. At first I was worried no one would reply. Thankfully, 10 of you did. I had trouble picking my favorites because there are so many different angles to take. Some were detailed explanations, others were great conversations, while others were just downright hilarious. I wanted to make sure everyone who contributed got something. I decided to go with four prize levels. For those who participated: my rankings are arbitrary and don't necessarily reflect the quality of your writing or of your ideas on money. If anything, they're probably influenced more by whatever I ate for dinner tonight. Either way, I picked some I liked so we can wrap this up.
After posting this, I'll send each of you Steem Backed Dollars for your efforts. The introduction post for this challenge made me 217 SBD and my own entry made 16 SBD (not including any Steem Power). That comes to 233, which I then doubled and rounded down to 465 SBD for the total prize pool.
Level 1 Prize - 100 SBD
Steem: Where DOES the money come from?
This was actually written a month ago, so it didn't have the #bitcoinpizza tag, but it was entered via the comments, and I'm allowing it because it's just such a great write up. If you haven't already, go give it a read.
Level 2 Prize - 75 SBD

You might be asking, why did Luke spend his own money on this? That's a good question. I'm not really sure. I am sure that I want more people to think about and question their own understanding of money. So many people work every day to earn money and pay bills without even thinking about what it is. I'm hopeful Steemit can change this. It won't come about just through technology. It requires that we, as members of the community, continue to challenge our own thinking and skill up.
One of the best posts I've seen so far on this topic came from 
Where The Money Comes From - "Digging Deeper Into Steem" (Part 1)
In that excellent post, he also links out to these gems:
My Journey Peeling back the Economic Layers of the Steemit Onion...

I hope you'll take the time to read through these and continually skill up your understanding of how Steemit is creating a new form of money. This money won't be backed by coercion or government decree. It won't be controlled by intentionally convoluted, cronyism policies. It won't be restricted to imaginary physical boundaries.
The future money of Steemit will be what we make of it. Let's get our understanding right from the beginning.
Thanks again to everyone who participated and put themselves out there to better understand money and think through how to explain it to their friends and family.
