Just chilling and sharing a stream of thought…
So how would a credibility system work and be implemented. What I envision is something similar to the up votes…
You have a credibility score, it starts a 0 neutral. You post something People don’t vote on if they like, the votes are for “good faith”
Good faith is You posted according to rules and started a discussion You argued in good faith and can separate with opposing opinions You clarified a topic for someone If someone has a polar opinion to yours and is being down voted because people don’t understand the system Etc.
It is tied to the user not the post
Good, bad, indifferent…?
Perfect the system
You know that the current voting system isn’t like/dislike, right? Or it’s not supposed to be. Your proposed system would have the same problem: users would use it as like / dislike buttons.
