Dear Lord in Heaven, I used the "u" word. I have been working on a brochure for one of my clients for the past couple days. After seeing and using the words unparalleled and exceptional, I (hanging my head in deep writer's shame) actually used the word "unprecedented." I wrote about it here and now I have joined the crush of media who have used the word.
I also hate the phrase "24/7," especially in commercials, but it is sometimes the most effective phrase to describe around the clock service or whatever and it doesn't bug me as much in writing. So I have used that one too. Sigh. I have now officially compromised my copywriting ethics and confessed this indiscretion. I feel better already.
