Dear @diogosantos
Joe needs to do much more than good quality posts, just like in any other platform.
You've nailed it.
But Joe is lazy :) Joe doesnt want to spent hours reading comments, and finding quality content himself. Joe doesn't want to put more effort than minimum (posting his own content)
And Joe would like STEEMIT to solve problem of this laziness. Perhaps you're right that things could get better, but core of problem is not "tool" (steemit platform) but that general laziness and belief that quality content should promote itself.
Cheers,
Piotr
