I'm troubled by the tone of some responses on here from time to time.
It's a great forum for listening and speaking about intricate issues, or getting a quick update or temperature-check on fast-moving situations.
Inevitably it also attracts questions from students, from interested amateurs, and from practitioners who perhaps don't work to the highest standards (but that's the price of democracy and easy access). Sometimes these questions betray misunderstanding on the part of the questioner. Sometimes (oh horror!) they repeat material covered in earlier threads.
I feel that if you are someone who is troubled or offended by such questions, you should ignore them. Sarcastic or high-handed responses don't show the profession in a good light, especially not when they are directed at students or new entrants to the profession. I really do wonder at the attitude and outlook of those who seem to want to use this forum to 'clip the wings' of those who...what? Don't deserve to be here?
So endeth today's sermon, and thank you for listening.
