Now, it's about a lot more than money to me. See my recent entry here https://steemit.com/steemit/@lukestokes/explaining-steemit-to-my-friends-blockchains-and-cryptocurrencies and my intro post to better understand where I'm coming from.
I had someone explain it to me in terms of the 80/20 rule. We see that everywhere. When we try to fight it or force things to act otherwise, it fails. As for what qualifies as "good content" that will depend on how the community grows. It's relatively small right now.
