Google has just launched SearchWiki within their search results. This toolset allows users to alter the results that they receive from google. They can move results up or down, add new results, or even remove them from the results. You can also add comments to search results.
Now, I should make it clear that this does not affect page rank, or even the results that other people see when doing searches. However, other people who are logged into google can see, via the SearchWiki icons, what users are doing with results. This allows the SearchWiki community to function much like reddit or Digg.
We’ve always said that the best search engine is the one that understands what the individual user wants … SearchWiki really puts that in action: this is an even deeper level of customisation than we’ve offered before, because people know best what search results they are looking for.
Juergen Galler, director of product management at Google
This is a great step forward for google. Rather than entirely trying to mathematically determine optimal search results they are actually able to incorporate opinions from people who are doing the searches. So while this won’t have an affect on most googlers, it does allow them to start to harness the massive community of people out there who want to work together to find better results.

I can only hope that this is a start of something that will provide more power to the social networks of users who are depending on google every day. Moving google a bit more towards the digg/reddit model could help to make results more relevant and also drive more involvement. Of course reddit and digg are also gameable, often times political or underhanded forces take advantage of this to bias results on the front pages of these site. Google is no where near prepared to give their rankings or results over to the mob. This method does seem like a safe way to allow those crowds to have their say without jeopardizing Google’s standing as the best way to search. Learn more about Google SearchWiki:
