In some way, didn't Google become Alta Vista?
I have used Google since probably 2001-2002 sometime and a number of other search engines before. It is rather obvious to me and I have writing and screenshots from around the time quality took a dive that supports it.
Back then I think people mostly agreed that the results that ranked on top in Google generally were there because of criteria that benefited the end user.
I mean, even as crazy as Google results has been the last few years they have still managed to be better than Bing and DDG who both manages to have worse ranking and also like Google completely ignore my doublequotes.
