Omitting clarifying information is how cool kids signal their coolness to others, and exclude uncool kids.

This is even more true of HN users than it was on the actual playground.

Titles tend to be terse, HN—by the guidelines—prefers original titles, Kleppman isn’t (AFAIK) an HN user, and the piece is ~20 years old—when a lot more of the audience wouldn't have missed the reference.

Yours is a response to someone providing clarifying information, something I often find helpful on HN.
