The American novelist Jonathan Franzen (whose work I believe to be overrated) reportedly has declared that Twitter is "unspeakably irritating" (see here). How could that possibly be true, when it is so easy to ignore Twitter's existence (as I do everyday).
Perhaps Franzen is irritated by the simple fact that the word Twitter comes up so often in conversation. But reading his comments in context, his issue does not seem to be with the word itself but with the notion of trying to make fact-based arguments in 140 characters or less. But since no one's forcing him (or anyone else) to do that, why does it irritate him so much? He can always blog instead, or write another grandiose book.
