You bring out a good point differentiating contribution and content.  I create some content which I saw AS my contribution... but to really make my posts and the website as a whole better... what am I doing to contribute aside from creating content... Perhaps that is enough for me, but people also need to contribute in ways you suggest on your list.

I think we are pretty close to your version of steem now where there are 100 or so posts that make 95% of the money.  The fairness that you speak of is merely a plea from those that don't understand the role steempower plays in this ecosystem and are looking for something for next-to-nothing.  Granted, there are some fantastic posts that go unnoticed due to this... but perhaps if these posters  thought about things such as this... they could become more visible.
