In your responses to anyone anywhere, I would ask you to remember there is a difference between "I see your struggle and I want to be helpful to you" and "You're doing it wrong and I want to be the one to say that to you" and also a difference in how they will be taken in by others. If you don't know the difference between the two (or don't care), perhaps it would be best for you not to say anything at all.
@scalzi Something I've struggled with, and have tried to get across the line to the right side of. Silence is golden, of course, but even better to just be good.
