Matt would you comment on the thought process of Google on curation. There are sites that are generally strongly disliked. Examples: Demand Media in general. Or say w3schoolS.com for JavaScript/CSS/HTML. I can understand that there would likely be a deluge of legal action against Google if this was done in a heavy handed way. Or is it a principled thing where everyone should be treated equal? If so isn't that a lot of algorithm ideology. In practice hard rules without human judgment leads to ridiculous edge cases or bypassing the intent of the rules. I always assumed you curated in a way via having teams that specialized in creating topic specific search techniques which then all get combined together via topic detection or some other meta algorithm. This would be a good balance between manual curation and having it be a scalable approach.
