Google SearchWiki, Customize Your Search Results
Google has just launched SearchWiki which allows you customize your search results.
Today we’re launching SearchWiki, a way for you to customize search by re-ranking, deleting, adding, and commenting on search results. With just a single click you can move the results you like to the top or add a new site. You can also write notes attached to a particular site and remove results that you don’t feel belong. These modifications will be shown to you every time you do the same search in the future. SearchWiki is available to signed-in Google users. We store your changes in your Google Account.
