Blair,
We all know that person has Neurosurgeon or Orthopedic surgeon credentials behind his or her name...(not) ~

My reaction to this reply would be what yours is since I find it useless in terms of constructive critisism or by way of shedding new light on this topic so near and dear to your heart or more succinctly your spine. If I were to respond to the poster I'd definately have to wait until I had simmered down a bit so my reply would be much more neutral. I'm not sure the person posting that reply deserves any further of your thoughts/time ...
