WTF!? So that, plus "Risked BTC amount", plus "or had a successful trade"...
Well, it seems that you are confused about it. I tried to clarify that there's a huge difference between adding a ~¨and keeping/removing a rating from someone. I tend to rarely leave positive ratings, regardless of whether there were deals with someone or not. 
Can Bitcointalk's feedback system have just a single aspect that isn't a steaming pile of useless shit?
IMO it isn't too difficult to understand if you give it some time and think it really through.So, you understand it well enough to rarely use 1/3 of the steaming pile of useless shit. Why then, should the forum have any rating level other than negative?
I do remember reading theymos' post somewhere that the new forum was going to be released "next year". That was multiple years ago.
That doesn't necessarily imply a completely revamped trust system.With this much donated & ongoing transactional BTC at stake, why in the fuck would we want not only to keep Bitcointalk SMF's feedback system a steaming pile of useless shit because dev time is ostensibly focused on the new forum, but to also celebrate the release of the new forum with a similarly-steaming pile of useless shit for its feedback system?
