HN is a public forum for sharing news with a large group of mostly strangers around the world. Quibb is for sharing news within a very small and private group of people that you work with and all the speech and thought restrictions that implies. That's not very high overlap. Anyone can convince themselves this is their ideal audience and get some iota of validation by pooping out articles for us.
