Utterly
I'm never sure whether these things come in waves, or whether I just notice them in waves, but in the past few weeks, I've seen quite a few stories that use the verb uttered in place of said.
In general, I wouldn't use the word uttered in fiction except in the most eldritch of Lovecraft impressions or the highest of high fantasy. (Um, I'm talking about using it with a directly quoted line of dialogue; it stands out less with an indirect quotation. "'Damn,' he uttered" doesn't work for me, but "He uttered an oath" sounds a little less weird to me. Though still probably a tad old-fashioned.)
I should note that I don't particularly dislike "said" bookisms (verbs used in place of "said") on general principles. I often quite like them, in fact. And I disagree with those articles and teachers who say that facial expressions and other actions (smiled, frowned, sobbed, etc) can't be used as speaking verbs; it seems to me that they're simply shorthand for speaking while performing the indicated actions.
However, I do agree with everyone else that "said" bookisms (what a clumsy term!) can be and are frequently overused, and that some of them don't go over well with modern readers in a modern-setting story. What I don't like about uttered is that it sounds archaic and melodramatic to me.
I started to list some other verbs in that category, then realized there are too many of them. So just take it for granted that uttered isn't the only speaking verb I recommend against using; just the one I've seen most often recently.
Standard disclaimer: I would never reject a story, or even stop reading it, because of a few jarring words. But if there are a bunch of them, it does make me less favorably inclined toward the story.
