If you ever tried Augur, Fairlay, Delphi, and other prediciton platforms, you will find that these platforms are still at their very early stage. The user experience is bad and the platforms are under performing since so few users have registered and traded on these markets and the prediction market relies on a large number of participants in the market to make it efficient.
But besides all those problems, I wanted to propose the one that has been missed on the platform: too few content.
Let me jump to the core statement underlying: there should be a Steemit platform working with each prediction platform, so that every user/better will get enough feed of content before they make the bet or trade.
