I'm on steemit since few days but I followed this platform in the first days.
I totally agree with you, the potential of this platform and the technology behind is huge, but the greedy risk is high and real.
Bidbots, promotions and greedyposting is a real issue here, that's why I feel really happy and proud when I see a well done post in the trending page or in my feed.
Steemit could completely change the social networks world, making them really social and less money-driven, but we must do our part (from the user that start posting yesterday to the whale that is using steemit since the first day).
Great manifesto, keep it up!
