You can say : "sorry it doesn't talk a lot about design. It fell like an ads."
It was about the tone.
Also, but that's not your fault, it may hurt fellings of long term contributors because that's not an easy task, we spent several hour on finding content and sharing them while handling the moderation part. We are a very small community on the threadiverse, so we endorse several role.
And there is little reward at what we do.
So when a new user react negatively, most of us are sensitive but that's not an excuse for us to go overboard against users.
That's all :)
Btw, what kind of design do you enjoy ? Car ? Architecture ? Object ? Typo ? :)
