I think there's no perfect formula, as others have said.

I do believe the principal that you get what you give. It may not happen on the timeframe we want, but the principle holds true over time. This principle also, theoretically, shakes out people who are too selfish if the community is healthy.

So I do believe that Steemit should use this as a guide without being too rigid and forceful about it. Allow space for various personalities, in other words.
