I did just that a week or so ago on Twitter (maybe the incident to which you're referring Tim?) because the advice was so blatantly misleading from such a widely read blog - it would have had many DBAs struggling to figure out why their system wasn't exhibiting the behavior specified.
Paul, this editorial was written a few months ago, so any similarities to recent events is purely coincidental 🙂
But you're right - the same method doesn't work for everybody. Nobody wants to hear that their baby is ugly, but some people respond to it better than others. It's a fine line to walk, knowing how to gently correct without alienating a well-intentioned writer.
