My problem with the thread is that I presumed (I believe, correctly) most people here would define as "smart," the people who agreed with them on various subjects or who dazzled them with their long winded or snarky posts. None of those define smartness, in my opinion.
I don't think that is a problem with the thread. It is a problem with anybody who uses that specific definition of smart.
It was not up to me to define "smart". I could had but that is only one perspective.
There is a plethora of definitions for "smart" in this thread and reading and considering all of them helps to give one a greater meaning and appreciation for the term...and for the posters who we assign that term to.
