Is there a genuinely good reason for all the notes on various images to correct grammar, spelling, etc.? I feel they are usually far more distracting than the errors, and don't serve any real purpose (beyond letting the annotator have a cheap, brief feeling of smugness). I wouldn't mind them in such rare cases where the English is so bad as to be nigh unintelligible, where they're added to actually clarify the author's meaning (i.e. translation notes, basically), but I've never actually seen one like that here.
Is there any reason I shouldn't just delete notes that only serve to highlight very minor language flaws?
