I'm not arguing that writers do not want feedback, though. What I'm saying is a) so what? Our wanting feedback on our work doesn't mean anyone has a moral prerogative to provide it to us (good lord, if ONLY the world worked like that!); and also b) Kudos ARE, in fact, feedback. The word means "honour; glory; acclaim", actually, so they are (at least nominally) pretty high praise. They may also be a little rote and generic and non-specific, but so are a lot of supposedly handwritten comments. C'est la vie, you know? At least it's not silence, which is by far the most lackadaisical, most ambiguous, least helpful most common feedback writers tend to get on their work.
