Even though I know what in means when someone says it, that doesn’t mean I don’t find it really annoying. When someone calls the first movie SW, it makes them look like someone stubbornly stuck in the past who is against any and all change, regardless if it’s an improvement. It sounds as stupid as arguing that the shift from black and white to color was a bad idea. A post on Jedi Council Forums says it best in that it should be called A New Hope for the same reason we call it World War 1 and not the Great War as it was originally known.
