No I'm not that catagory and I don't care that members trust rating when I'm reading, if he/she adding value to the ongoing discussion.
Yes, but what about ranking? For instance, try to imagine that someone got's an underserved redtrust as a payback from a personal issue with someone, for instance.
If they were trusted and they lost their credibility -just if that' s the case- then, what happens with the trust they give to others?? Sorry, my brain is just exploding here. 
Actually, you're making a good point here and I'm thinking red trust given by particular DT member, should be removed (Not other members given) if that DT member lost their credibility. but, being honest, I would think twice before meriting someone with red trust. I guess that is why this isn't shown in all boards because it can subconsciously influence the people about the one writing.
This is what theymos said about giving away your Merits (theymos didn't say anything about trust
)While we will not be directly moderating this, I encourage people to give merit to posts that are objectively high-quality, not just posts that you agree with.
