By the way I did not notice this change before, but after reading the OP post, I just reconfirmed and found that yes, the trust display is missing in the Bitcoin discussion section.
Well that's his exact reasoning and I have seen people use people's trust score in arguments before before as an off topic ad hominem attack just to dismiss what someone is saying, so it can and does influence how some people perceive others even though it might have nothing to do with the topic at hand.
Well, then can't this type of behavior be seen from the member's ranks as well? Anything said by the Legendary member usually has (or is perceived as) a higher weightage than anyone's else point of view especially if it is said by a Newbie or Jr Member. I am not saying to remove the rank display from these boards, but just sharing an observation as a whole.
