Hey everyone!
I'm professional analyst who works on managing content of a platform with free posting system. I can tell you how difficult this task is. And it becomes even more challenging if your platform is non-profit when you don't create money from your content.
So my vision of steemit future is a couple of commercial or semi-commersioal platforms on top of steem blockchain with complicated and powerful content managing system each competing for user's views.
Someday I'll write a full post about it.

Cheers!
