I endorse discussion of virtue ethics on LW mostly because I haven't seen many arguments for why I should use it or discussions of how using it works. I've seen a lot of pro-utilitarianism and "how to do things with utilitarianism" pieces and a lot of discussion of deontology in the form of credible precommitments and also as heuristics and rule utilitarianism, but I haven't really seen a virtue ethics piece that remotely approaches Yvain's Consequentialism FAQ in terms of readability and usability.
