copy and pasting posts is one thing. Steemit's proof of brain is most interesting because it has evolved directly out of social media where ideas were rewarded with likes and popularity which meant no physical reward except for the most popular by way of corporate sponsorship, similar to top athletes. steemit takes the centralised (zuckerberg gets all the cash) model and distributes it. I find as a steemian with genuinely original content. ( I am a creative professional) with over 20 years of experience, my content doesn't get rewarded commensurate with it's merit. I see total crap making hundreds of dollars all time and I never score that highly. There is another force at work here and it's to do with the power of social networks and currency. In the normal centralised model, there is the opportunity for success through virality. However virality often takes more than seven days to achieve. Steemit will evolve a virality function (the ability to earn past seven days) and then it will reward more fairly content with artistic and intellectual merit. Merry Christmas. On the flipside, my meagre rewards can be traded for their real value with an extra twist to the equation. swap the tokens for ones which increase in value faster than the platform rewards. This is most satisfying. It's like finding pennies and turning them into more. magic beans indeed said Jack's mother.
