Some thoughts.
[1/2] I used a lot of #QT on twitter, always constructive. But my 6 weeks here have convinced me that the #noQT custom imposes a healthy discipline on all of us, even absent any bad-faith actors. It makes us listen.
If I QT another person's post, I subordinate their post to my own contextualisation. That sounds good, but it puts my judgement first.
Let the original post speak for itself.
