Pinker makes some persuasive arguments for abandoning to some degree such rigid interpretation of grammatical rules, where usage has evolved.
We would do well to abandon such sniping and focus on the meat of what an author is saying, so long as the meaning they convey is clear.
Shall we lower our standards so we all speak more grunt-like? Is this where we are headed?

FWIW, with respect to the HN rules, it is frowned upon to comment on voting:
> "Please don't comment about the voting on comments. It never does any good, and it makes boring reading."
I think that 'guideline' about not commenting on voting is circumspect, because it means that people, in the heat of the moment, can press a button when they are pissed off, and don't have to craft a logical response ('the why'). It cheapens HN, I believe, and I'll mention this to Paul next time I see him.
When an author, none less, writes incorrectly -- it makes me question his basic thesis.
