Changing some one's mind is a bit harder than adding code. But as far as the culture change steps need to be taken in order to keep it sustainable. One first thought is Witnesses get way to much to run a node server we all know less than half of the witness only run a witness node and nothing more. Now that's not to say they are doing nothing for the network (They maintain the integrity of it)

Bots are also a huge factor more and more accounts are just delegating for the sake of earning. If we could do half and half for curators the bot army will subdue. Author/Curator Win win more eyes on real content and less automated content, thus creating a social network where both collaborators work hand and hand.

SMT's are a way of coating the stink that surrounds Steem and Steemit.

"Let's create different tokens on top of Steem... yup that should help create real communities" I see none of this happening but worsening the effect.
