As a professional, I do not make comments on such topics in a forun such as this. When asked I say truthfully “I have no comment”.
You can avoid being negative and still get your message across. And not make our profession appear less professional.
I do occasionally use the thumbs up or down to point out clearly good and clearly bad advise. Those getting the thumbs down can contact me to ask for an explanation. I don’t use this feature lightly and always have support for the thumbs down that isn’t from information that I got off a Yahoo! article or some other “psuedo-news” site.
