For reasons that are opaque to me, an inordinate number of people without basic grammar skills go into, of all things, sign-making as a profession. The result is the ubiquitous phenomenon of quotation marks used inappropriately for emphasis. I was on a Muni train today and saw a professionally printed sign reading:
You are being videotaped.
In other words, the San Francisco surface rail system is not really warning you – just air-warning you. Pretending to warn you. Mock-warning you. “So-called” warning you. Got to joking with a MacWorld editor about this phenomenon and he turned me onto The Gallery Of “Misused” Quotation Marks, an archive of misused quotation marks in the wild. Hilarious.
Was also amused by the resemblance of this site’s name to my own Archive of Misheard Lyrics.
