Great Post, but i don´t agree with the conclusion.
I think steem really should copy it from Facebook somehow.
Money has to come in somewhere to be redistributed, and at Facebook for example. people like sites like coca cola and mcdonald´s because they are willing to see the stuff. and if you don´t follow the originator already, an algorythm should choose (wisely) what you might like to see.
So in the home category should also be things like: the person you follow did upvoted that....
are acording to your... this might be interesting.
Steemit just have to make sure, that these things will happen in a free market with not a one party choosing everything like facebook.
