here people can present fake comments because they can hide behind fake names.  when the commentator is known, the audience can better select with which to identify or not.  this is one of the main causes of the mis-directions in today's fragile and often chaotic thinking processes of our society!  simply parroting or re-hashing what someone else has said is NOT FACTUAL unless it is verifiable and quotable with footnotes - like in college!  like the lady said - we had to show all our work in deriving any math solution.  in trig class we had to cite the proper axiom and /or corollary to substantiate our methodology.  in expository writing we had to cite the source, any source, properly and accurately.  written project or job specifications all had to be checked, re-checked and re-checked again before being submitted to bid RFP's.  despite all the haste in getting the job out, correctness could not eliminated for the sake of expediency!  this applies to knee-jerk responses also!
