I'm OK with leaving feedbacks and I should do it when it's needed, even my feedback as non DT member don't have that much weight. But I have no intentions to become DT2 or DT1 member. I really don't want that someone would analyze my trust list, my judgement and etc. Less centralised trust system is good thing, but no, I'll stay away from these things as I used to do during all my time here.
Even you're not included any user in your trust list, but if there's a DT1 user include you in his trust list, you will become DT2 member.
Based on my observation, don't need to worry if someone analyze your trust list, your judgement etc, as long as you have a reason, you can explain it. If you want to avoid drama, don't distrust any user

many users get offended when someone distrust them. Distrust is important, but it will cause a drama,.
I'm not a DT member, but that's what I understand so far.
