It may be the proliferation of things like text messaging and Twitter, but punctuation seems to be sliding into extinction. Often, where it is used, it is wrong (see the number of times people use apostrophes in inappropriate places). I'm reminded of the example provided by the writer Kingsley Amis, who provided a wonderful example of why we need punctuation. Compare the two sentences: Those things over there are my husband's. Those things over there are my husbands. One little apostrophe, one big change of meaning!
