This is indeed a good post and I believe the devs are doing everything in their power to promote quality content. The survival of Steemit, as well as substantial wealth, depends on it. That said, no one can change human nature and human nature is generally crass and shallow. Boobs and quick laughs are going to get the spotlight and that is never going to change. It is very hard to automatically identify quality content and that is why Steemit pays for curation. The absolute best thing you can do to improve visibility of quality content is invest time commenting and upvoting, as I am doing here. Great post, thank you and keep them coming!
