@plainoldme,
I'll speak up for mysteryman too (as you do here). I always read what he posts, when I see it. I tend to read GeorgeOB and Finn but sometimes skip along. Roger is conservative to me in the original sense (not that I can define that), always readable. All these mentioned are different from each other, a spectrum of people I'll listen to, sometimes. I know there are more conservative a2k posters I get, these more immediately coming to mind.
I have to admire, or at least am in some kind of awe, at posters who continuously engage with people they think are repetitive goofs in some way. I simply don't have the interest. Our ideas re goofs may vary, and I'm sure I'm another a2ker's goof. I don't understand the energy going into it. On the bad side, this feeds them, whoever they is. On the good, arguing can put one's points out there yet again and again.
