I don’t think curation is the answer, if Wikipedia was based off rules and if fundamental articles were dependencies to more complex downstream articles I think people would have more respect the site. Curation invites unintentional omission of information which people may suspect is intentional. If a Wikipedia model first defined rules for a genocide article and then screened events that were suspected to be genocides against the genocide article then a more uniform interpretation of genocide across the entire site would be possible. I think the goal for Wikipedia is to avoid inconsistency, to cover every viewpoint in a topic with rationale and to do so truthfully with associated references.
