In an effort to provide a more customized search experience, Google has launched a new feature that lets signed-in users shift around, delete and add comments on search results. The feature is called SearchWiki, and it is a dramatic departure from the streamlined, algorithm-rules approach to search that Google has championed for years.
The company has been testing this system in its labs for a while, but now it has seen a full release. It's not clear whether Google plans to incorporate user feedback from SearchWiki into its normal search results eventually, or perhaps they simply plan to consider the extra data when determining the relevance of its own rankings.
Moreover, Google was careful to point out that the system would only affect personal results, but it will nonetheless allow you to see how the community has collectively edited the search results by showing notes made by others and what pages they have re-ranked, added or deleted.
