Preemptive critique of the times story: it's possible that one angle that might pop up is "wikipedia takes a relative approach to truth: wikiality: truth is whatever the mob says."

But NPOV and concensus (and a hands-off approach toward differing cultural norms) are not academic philosophies of knowledge, they're practical approaches to the process of collaborative writing, imperfect but workable solutions that allow wikipedia to (dare I say) thrive.
