I think part of this is important too because online news articles might have corrections, or certain paragraphs might get deleted in some rare situations. It's good to have a way of tracking those. Sometimes, the edits made to an article are very irrelevant to the actual message. I'm thinking stuff like typos, or even embarrassing gaffes like the recent time that a headline implied that the NATO acronym had the word "American" in it.
