> The idea that Search is somehow worsening doesn't make any sense.
Search is worsening. We've all seen it with our own eyes. I don't care how much analytics Google is gathering, that's irrelevant.
Just take on example: try googling for the release date of an upcoming video game or movie which you know for a fact hasn't had an announced date. Then view the top 5-10 results and let me know if you consider them to be of a high quality.
