Neil Neches of the New York City Transit's marketing and service information department gained fame when he inserted a semicolon in a public service placard:
It was nearly hidden on a New York City Transit public service placard exhorting subway riders not to leave their newspaper behind when they get off the train.
“Please put it in a trash can,” riders are reminded. After which Neil Neches, an erudite writer in the transit agency’s marketing and service information department, inserted a semicolon. The rest of the sentence reads, “that’s good news for everyone.”
Which brings the question: why aren't we using semicolons more often? (I blame conjunctions!)
Ironically, The New York Times article itself contained a punctuation error (see errata below). Oh, the irony!
