Google is getting so much worse. Seriously. I've tried searching for `49ers -football` and naturally the first page is filled with football, and the first link about the gold rush is on the second page. Excluded terms with the minus sign are only downranked, and of course sponsored links ignore your downranking. If you're not looking to buy something, Bing/DDG is slightly better, but they still do the thing that what you type is just a suggestion.
