I usually include a note that I've been seeing this [whatever] in a number of different places, and that my comments aren't aimed at anyone in particular.
Invariably, that note is ignored, and at least one person will respond most heatedly as if I were in fact addressing them specifically. It's not just a matter of getting defensive about their position; sometimes, they will come right out and say "you didn't need to take this public".
You know who you are. Don't try to deny it. Yes, I'm talking to you. You're the only one who has ever done this.
You may have noticed that I run a few "sub-columns" in this journal, usually identified by headers. The Hoard Potato talks about mass media, Understating Athelind's Argot discusses peculiar turns of phrase that I use, Film at 11 talks about the news of the day, and so on.
From here on, when I make a broad response to something that more than one person has brought up that annoys me, or that I feel needs response, I am going to use this header: You're So Vain.
Just for you.
