All that is required to transcribe that quote correctly (and a few others in the article) is to use a semicolon instead of a comma.

Oh, I know. One of my friends noted the same thing recently--people use semicolons all the time in spoken language. But in written language it looks pretentious somehow.

People don't use semicolons in speech — they use emdashes.

I always wondered what a semicolon sounded like.
