He gave no facts, no observations, nothing concrete. Just a broad slam and a question. "I don't use P5... what does that tell you?" That tells me nothing but that there is some unstated reason for him not using it. Why ask me that? My own answer could be "Maybe there is a business or political motive." When you use your name, or position, or perception of power/authority to back up your arguments instead of facts or observations, it is using "argument by intimidation." So, since this guy, whom I respect, says P5 is no good, should I disregard my own knowledge and experience and just quit using it or discussing? No. The name will not sway me, nor should it anyone else. I did not say ALL negative comments about P5 are baseless. And ynsaen said much the same thing in one of his posts. I felt compelled to mention the negative comments since radeon brought up the point that these comments were influencing his decision.
