I think most people would go where they are getting $40 dollars versus 40 cents. Further at some point i.e. when your payouts become next to worthless you don't have any benefit left versus other websites that don't pay you.
We must also be wary that there are several alternatives and someone could easily spin off their own version of Steemit that gets this right.
I don't see the compelling reason to keep the SD on that basis.
