So, we must carefully consider what really signals intelligence.
Linguistic errors pale in comparison to errors of understanding like missing the point.
Discussion should be about connecting and learning, not one-upping.
This distinction is why the Internet 'communities' almost never are. Nerds love to be pedantic while not realizing it doesn't add anything to the discussion. Actually, it potentially poisons the discussion, steering it towards who is more right, rather than actually, y'know discussing things.
