An interesting thought. But no matter what Steemians wish to think, Medium is out of reach of Steemit... I still hang around Steemit, but there is not much to read here. But there are tons of high quality posts in Medium. Everyone has only limited amount of time, and thus needs to wisely allocate time. It's totally rational that expectation of payout in Steemit is one of many factors in the equations to determine where to allocate limited resources. But in my equation, the higher probability to find a high quality posts in a certain limited time is of much higher value.
