That's a nice and unexpected answer, so I'll continue asking questions I have no clue about :-)
If metaethics doesn't influence paperclip maximization, then why do I need metaethics? Can we point out the precise difference between humans and paperclippers that gives humans the need for metaethics? Is it the fact that we're not logically omniscient about our own minds, or is it something deeper?

Well, there's certainly that. Also, human algorithms for decision-making can feel different from simply looking up a utility - the algorithm can be something more like a "treasure map" for locating morality, looking out at the world in a way that can feel as if morality was a light shining from outside.
Do you believe in an objective morality capable of being scientifically investigated (a la Sam Harris *or others*), or are you a moral nihilist/relativist? There seems to be some division on this point. I would have thought Less Wrong to be well in the former camp.
Edit: There seems to be some confusion - when I say "an objective morality capable of being scientifically investigated (a la Sam Harris *or others*)" - I do NOT mean something like a "one true, universal, metaphysical morality for all mind-designs" like the Socratic/Platonic Form of Good or any such nonsense. I just mean something in reality that's mind-independent - in the sense that it is hard-wired, e.g. by evolution, and thus independent/prior to any later knowledge or cognitive content - and thus can be investigated scientifically. It is a definite "is" from which we can make true "ought" statements relative to that "is". See drethelin's comment and my analysis of Clippy.
