Try to make every moment worth repeating.

It's attitudes like this one, (from a recent commentary)

"public embarrassment is more powerful than a mere correction. You are going to remember everything [sic] seeing what a fool you were a lot more than someone correcting what you think is a minor "whatever". The point is to make it clear sloppiness with units is NOT a minor issue."

.. that make me despair for the future of civil discourse on these exchanges.
