Google Concedes Yahoo has the Answers
I think Yahoo should leverage their del.icio.us property to improve their search product. They could tack on del.icio.us results, much like they've done with answers. Better yet, they could use the collective intelligence of social bookmarking to improve their search relevance algorithm. Google's big breakthrough was PageRank which uses links as a measure of a web page's relevance. Google looks at both the quantity and quality of links and treats these links as, essentially, votes for a site. I think a page bookmarked via del.icio.us could be a better indicator of the importance of a web page than links. Particularly as webmasters have caught on to this idea and links have been gamed to a large degree. If someone views a page as important enough to bookmark, perhaps that's a better "vote" than a link? If Yahoo integrated del.icio.us bookmarks in its search engine algorithm, could the results be more relevant than Google's?
Time is another factor. With current search engine technology, it can take weeks for a web page to show up in the SERPs (search engine results pages). It takes time for crawlers to find a web page and then index it. A new web page could be very relevant for a given search result but not be present. That new web page could propagate very quickly through the blogosphere and be bookmarked by a large number of people in hour or days, not weeks. If Yahoo leveraged that collective bookmarking, their SERPs could be fresher than Google's. If Yahoo updated their SERPs on even just a daily basis and included web pages from the del.icio.us popular and recent bookmarks, could their SERPs be more relevant than Google's? This might even obviate the need for a separate blog search engine (like Technorati or Google blog search). How about it, Yahoo? Use some of your peanut butter and stick del.icio.us to search!
