I had some points on the DT system changes a while back but I'll restate them since looking for them would be too much work:

The increase in DT1/2 members means trust value dilution. This henceforth means that positive trust is generally worth less, evidenced clearly by the increased trust scores on many individuals (of whom previously had far less).

What I would say is that now, with the dilution of positive trust: negative trust is worth more in relation. It's nearly a reversal of what would be common prior to these changes: "neg more, trust less".

That being said, I'm sticking to my old firm criteria regarding positive trust but not imposing them upon other users.
