QuickTake: Is Yahoo Superior to Google?

I'm asking the question in the title because for two days now the Google Freakonomics count remained static, while it increased significantly on Yahoo. That suggests to me that Yahoo is updating their database more frequently than Google. If my conclusion is true, then if you are looking for the latest information on a topic Yahoo would be your best bet. More research needs to be done on this topic because I'd always heard that Google was the best search engine.
