Hmmm. Do I like it? I don't know. It's so easy to say and makes it easy to do something that otherwise is hard for people to do (admit a mistake). It would be cool if "mea culpa" were in vogue like "my bad" is - equally easy to say. I like its compactness - it's quicker to move on than it is with "Oh, sorry, that's an error," or "Oops, yeah, that was a mistake."
I don't have an aversion to it the way I did "... NOT!" that mercifully seems to have faded. And in a business setting, I probably prefer it to "oopsie!" ![Smile [:)]](/emoticons/emotion-1.gif)
One of the things I find interesting is how some people have a negative reaction to words or phrase, while the same phrase to another person is like putting on the most comfortably pair of jeans... I just hate seeing "wanna" in text, for example. And I hate that "vision" is now a verb in the buzzword lexicon of consultants.
