<i>Like Dave Winer, I am also 54 and absolutely do not care what anyone else thinks about it.</i><p>Perhaps that explains why you are also less likely to perceive it when it happens. Perhaps Dave Winer is more sensitive to this issue and that explains why he notices it more. I doubt that he is imagining this since you are one of the few people in IT that I have heard having a contrary experience. Perhaps you are simply an outlier.
