I read that example. It's factually incorrect if you take the comment literally, but if you understand the underlying point that the author was trying to make, it is a legitimate addition to the conversation.

This goes to show pretty clearly that someone's facts are someone else's opinion. How much of a nitpicker do you want everyone to be here?

Good point. I'd also note, however, that as hackers, we should attempt to be as precise as possible in our discussions.
