Annoyance is in the eye of the annoyed (or in the throat of the adenoid!).

What annoys me is incorrect spelling ("nieve", "tacher"). However, if I were to spend my time following chronic misspellers around the website and not only correcting all of their mistakes but berating them, insulting them and submitting posts with excruciatingly correct spelling under membership names similar to theirs, my behavior would be not only annoying but also QUITE rude; I would be more than a BIT of an ass, wouldn't I?
