And Agent|Austin's posts tend to be longer than one sentence, pauljanaway1 . (A big hint, there)
Yeah, I know. I'm nagging...
But seriously, my personal belief is that the number of actual posts is meaningless. I wouldn't have any objections if the count got switched off, given all of the people who seem determined to abuse it (that's my own view, not official policy).
I "rate" people (in my mind) based upon the usefulness and interest generated by their posts. You could post lots of meaningless single sentence messages and end up with a negative rating in my eyes...
