My initial reaction was that this response does contain accurate and sound advice. But the fact that it came from an AM, and the fact that it ultimately offered no direct practical positive suggestions really stepped out of the spirit of PM for me.

I must say, these statements have me boggled. You make three primary claims about the preceding post:

1. it contains accurate and sound advice
2. it was posted anonymously
3. it offered no practical positive suggestions

Not only do I find it difficult to reconcile points 1 and 3 --- accurate sound advice has always seemed of practical and positive value to me --- but that the anonymity of the post plays a decisive role in your finding it to be outside the spirit of PM is, in my mind, shamefully disappointing.
