It seems that all the major web search engines and webcrawlers are degrading in quality. The first thing they do now is return wikipedia at the top of the list with nearly all search terms. Search engine excludes from it's results any of those websites that just turn into an ad site, i.e. the companies that immediately register an expired domain name and sit on it with ads all over it. Those should just get excluded, maybe referenced to the internet archive project but start bypassing all of those. An optional list that is saveable of every website/host you do not want results from. I would put wikipedia on my list because the vast majority of the time it's not what I want.
