Keep in mind that if anyone wants to min max on this kind of environment it behooves them to cross post the same content on as many platforms as possible at the same time. If a second page similar to Steemit were to pop up then it, in a sense, doubles potential profits. All the user needs to do is post the same content in multiple places.

As long as a place like this can maintain some kind of revenue then the smartest people will never leave.
