Nice to see these kind of contests running. Please find my response and entry below:

1 - What was the most important thing you learned about SteemIt this week?
I learned about beneficiaries concept on SteemIt. Not exactly from SteemIt but while I was using SteemHunt and saw the detailed breakdown on SteemD of how the rewards got distributed amongst the beneficiaries SteemHunt has created for serving community with a platform on top of Steem Blockchain.

2 - Why did you think that was important to learn?
It is important to learn about this concept for the community to understand majorly 2 things:
a. How the DApps built on top of Steem Blockchain earn from it.
b. What percentage or amount of your rewards go to such providers.

3 - What was your approach? How did you find out about this? What did you do to learn this?
My approach included going on SteemD analyzing the payout transaction details to understand how it got distributed. I learnt that in actual fund was going towards 3 accounts- steemhunt, steemhunt.pay and steemhunt.fund
