I'm presently reading an eBook in which, every so often, an element of punctuation has been omitted. I've no doubt that the author got it right but the copy setter has been careless. It's not too hard to work out what's meant but that entails re-reading the sentence, or the paragraph, to see what it really means, And THAT drags me out of the story.
How do you feel about badly punctuated work?
