Modern search engines are yet another case of the tech world refusing to learn from other domains and dragging down everyone's quality of life as a result. People have been searching and organizing information long before computers. There is an entire field called library science.

Why is everyone so fixated on keywords for instance? They have their uses, but librarians and people who do research for a living also use subject headings. These are still human designated as far as I know.

People who are experts in an area often search directly by author. An actually useful tool would be something that cross-references advisor-advisee relationships, who was colleagues with who as a function of time, etc, and finds additional sources based on author networks. You maybe could do something like this for the web too, as I suspect a lot of high quality pages made by individuals are related by such interpersonal networks. A lot of spammy garbage sites probably have network relations to each other as well.
