I think the next innovation in search is crowd-sourced search. Users contribute directly to the index through a browser extension or somesuch. That way, you can get the site itself, how popular a site is by how many people visit it, and you also get the referrers. I experimented with this idea about a month ago. You can grab the source here (https://github.com/SeditiousTech/Avina https://github.com/SeditiousTech/Avina) and visit the index here (avina.apphb.com). It's not a real search engine per-se, but it is/was a pretty cool experiment. One of the problems is that people will forget to turn the extension off when accessing personal information (banking, porn etc).
