It pithily drove the point home for me: I had never been designing for users, but people.

"“The only people who refer to their clients as ‘users’ are drug dealers and technologists.” ... We still refer to “visitors,” “audience,” “consumers” when what we say we want are participants. ... We distinguish “creators” from ”consumers.” It’s a disconnect. While it’s just labeling, it has a great deal of bearing on our attitude toward the community."
Pithy quips emphasize cleverness of expression. The cleverness dazzles, and seduces the listener into agreement—but if you actually stand back and look at what they mean, they often fall down badly. Many very clever quips are shallow, meaningless, or just wrong, but they sound profound.
People very often don't bother with the "thinking about it" step though, and the result is that pithiness helps spread a lot of silly notions.
